MATLAB Programming 42 - Some array functions (1)

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:

zeros(5)

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

ans =
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0

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

For example:

ones(4,3)

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

ans =

1 1 1

1 1 1

1 1 1

1 1 1
