WebThe Matlab inbuilt method zeros () creates array containing all element as zero or empty value. This function allows user an empty array having a bunch of zeros in it. The Matlab programming language does not contain any dimension statement. In Matlab, storage allocation for matrices happens automatically. WebIf the size of any dimension is 0, then X is an empty array. If the size of any dimension is negative, then it is treated as 0. Beyond the second dimension, zeros ignores trailing dimensions with a size of 1. For example, zeros(3,1,1,1) produces a 3-by-1 vector of zeros. This MATLAB function returns the scalar 0.
