The ones() Function in Scilab

Within Scilab, the ones() function serves as a powerful tool for generating matrices or vectors populated entirely with the value 1.

ones(r,c)

Consider the parameters "r" and "c". They denote the number of rows and columns in the array, respectively.

Executing this function yields an array with the stipulated dimensions, uniformly filled with ones.

For a practical illustration, let's create a 5-element column vector:

ones(5, 1)

ans =
1.
1.
1.
1.
1.

Should you wish to produce a 5-element row vector:

ones(1, 5)

ans =
1. 1. 1. 1. 1.

For those looking to construct a 3x4 matrix with each element being 1:

ones(3, 4)

ans =
1. 1. 1. 1.
1. 1. 1. 1.
1. 1. 1. 1.

Venturing further, one can even generate a cubic matrix filled with 1s:

ones(3, 3, 3)

ans =
(:,:,1)
1. 1. 1.
1. 1. 1.
1. 1. 1.
(:,:,2)
1. 1. 1.
1. 1. 1.
1. 1. 1.
(:,:,3)
1. 1. 1.
1. 1. 1.
1. 1. 1.

For those scenarios where a matrix or vector of zeros is the requirement, the `zeros()` function stands ready for similar deployment.
