what is zeros in matlab code example

Example 1: matlab matrix zeros

X = zeros(4) % Creates a 4x4 matrix of zeros.

X = zeros(3,2) % Creates a 3x2 matrix of zeros.

Example 2: matlab zeros

X = zeros(sz1,...,szN) returns an sz1-by-...-by-szN array of zeros where sz1,...,szN indicate the size of each dimension.
For example, zeros(2,3) returns a 2-by-3 matrix
