All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array.

We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some special types of arrays.

Special Arrays in MATLAB

In this section, we will discuss some functions that create some special arrays. For all these functions, a single argument creates a square array, double arguments create rectangular array.

The zeros() function creates an array of all zeros −

For example −

MATLAB will execute the above statement and return the following result −

The ones() function creates an array of all ones −

For example −

MATLAB will execute the above statement and return the following result −

The eye() function creates an identity matrix.

For example −

MATLAB will execute the above statement and return the following result −

The rand() function creates an array of uniformly distributed random numbers on (0,1) −

For example −

MATLAB will execute the above statement and return the following result −

A Magic Square

A magic square is a square that produces the same sum, when its elements are added row-wise, column-wise or diagonally.

The magic() function creates a magic square array. It takes a singular argument that gives the size of the square. The argument must be a scalar greater than or equal to 3.

MATLAB will execute the above statement and return the following result −

Multidimensional Arrays

An array having more than two dimensions is called a multidimensional array in MATLAB. Multidimensional arrays in MATLAB are an extension of the normal two-dimensional matrix.

Generally to generate a multidimensional array, we first create a two-dimensional array and extend it.

For example, let's create a two-dimensional array a.

MATLAB will execute the above statement and return the following result −

The array a is a 3-by-3 array; we can add a third dimension to a, by providing the values like −

MATLAB will execute the above statement and return the following result −

We can also create multidimensional arrays using the ones(), zeros() or the rand() functions.

For example,

MATLAB will execute the above statement and return the following result −

We can also use the cat() function to build multidimensional arrays. It concatenates a list of arrays along a specified dimension −

Syntax for the cat() function is −

Where,

• B is the new array created

• A1, A2, .. are the arrays to be concatenated

• dim is the dimension along which to concatenate the arrays

Example

Create a script file and type the following code into it −

When you run the file, it displays −

Array Functions

MATLAB provides the following functions to sort, rotate, permute, reshape, or shift array contents.

Examples

The following examples illustrate some of the functions mentioned above.

Length, Dimension and Number of elements −

Cell Array

Cell arrays are arrays of indexed cells where each cell can store an array of a different dimensions and data types.

The cell function is used for creating a cell array. Syntax for the cell function is −

Where,

• C is the cell array;

• dim is a scalar integer or vector of integers that specifies the dimensions of cell array C;

• dim1, .. , dimN are scalar integers that specify the dimensions of C;

• obj is One of the following −

  • Java array or object
  • .NET array of type System.String or System.Object

Example

Create a script file and type the following code into it −

When you run the file, it displays the following result −

Accessing Data in Cell Arrays

There are two ways to refer to the elements of a cell array −

• Enclosing the indices in first bracket (), to refer to sets of cells
• Enclosing the indices in braces {}, to refer to the data within individual cells

When you enclose the indices in first bracket, it refers to the set of cells.

Permute 2

Cell array indices in smooth parentheses refer to sets of cells.

MATLAB will execute the above statement and return the following result −

You can also access the contents of cells by indexing with curly braces.

For example −

MATLAB will execute the above statement and return the following result −

Calculator Use

Like the Combinations Calculator the Permutations Calculator finds the number of subsets that can be taken from a larger set. However, the order of the subset matters. The Permutations Calculator finds the number of subsets that can be created including subsets of the same items in different orders.

Factorial

There are n! ways of arranging n distinct objects into an ordered sequence, permutations where n = r.

Combination

The number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.

Permutation

The number of ways to choose a sample of r elements from a set of n distinct objects where order does matter and replacements are not allowed. When n = r this reduces to n!, a simple factorial of n.

Combination Replacement

The number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are allowed.

Permutation Replacement

The number of ways to choose a sample of r elements from a set of n distinct objects where order does matter and replacements are allowed.

n

the set or population

r

subset of n or sample set

Permutations Formula:

For n ≥ r ≥ 0.

Calculate the permutations for P(n,r) = n! / (n - r)!. 'The number of ways of obtaining an ordered subset of r elements from a set of n elements.'[1]

Permutation Problem 1

Choose 3 horses from group of 4 horses

In a race of 15 horses you beleive that you know the best 4 horses and that 3 of them will finish in the top spots: win, place and show (1st, 2nd and 3rd). So out of that set of 4 horses you want to pick the subset of 3 winners and the order in which they finish. How many different permutations are there for the top 3 from the 4 best horses?

For this problem we are looking for an ordered subset of 3 horses (r) from the set of 4 best horses (n). We are ignoring the other 11 horses in this race of 15 because they do not apply to our problem. We must calculate P(4,3) in order to find the total number of possible outcomes for the top 3 winners.

P(4,3) = 4! / (4 - 3)! = 24 Possible Race Results

If our 4 top horses have the numbers 1, 2, 3 and 4 our 24 potential permutations for the winning 3 are {1,2,3}, {1,3,2}, {1,2,4}, {1,4,2}, {1,3,4}, {1,4,3}, {2,1,3}, {2,3,1}, {2,1,4}, {2,4,1}, {2,3,4}, {2,4,3}, {3,1,2}, {3,2,1}, {3,1,4}, {3,4,1}, {3,2,4}, {3,4,2}, {4,1,2}, {4,2,1}, {4,1,3}, {4,3,1}, {4,2,3}, {4,3,2}

Permutation Problem 2

Choose 3 contestants from group of 12 contestants

At a high school track meet the 400 meter race has 12 contestants. The top 3 will receive points for their team. How many different permutations are there for the top 3 from the 12 contestants?

For this problem we are looking for an ordered subset 3 contestants (r) from the 12 contestants (n). We must calculate P(12,3) in order to find the total number of possible outcomes for the top 3.

P(12,3) = 12! / (12-3)! = 1,320 Possible Outcomes

Permutation Problem 3

Choose 5 players from a set of 10 players

An NFL team has the 6th pick in the draft, meaning there are 5 other teams drafting before them. If the team believes that there are only 10 players that have a chance of being chosen in the top 5, how many different orders could the top 5 be chosen?

For this problem we are finding an ordered subset of 5 players (r) from the set of 10 players (n).

P(10,5)=10!/(10-5)!= 30,240 Possible Orders
