Return array in MATLAB

In MATLAB, we can create an array using square brackets [ ] and separate elements using commas or spaces. We can return an array from a function in MATLAB by assigning the array to the output argument of the function using the keyword return.

Here are some examples:

Example 1: Return a 1D array of numbers from a function

function output_array = generate_array(input_arg)

    % some code to generate an array of numbers 

    output_array = [1, 2, 3, 4, 5];

    return

end

Example 2: Return a 2D array of numbers from a function

function output_array = generate_2D_array(rows, cols)

    % some code to generate a 2D array of numbers 

    output_array = zeros(rows, cols);

    for i = 1:rows

        for j = 1:cols

            output_array(i,j) = i + j;

        end

    end

    return

end

The function generate_2D_array takes two input arguments (rows and cols) and returns a 2D array of numbers. We create an array output_array using the zeros function and assign each element to the sum of its row and column indices using two nested for loops. Finally, we use the return keyword to return the array from the function.

To call either of these functions and get the returned array values:

my_array = generate_array(input);

my_2D_array = generate_2D_array(rows, cols);
