ones
Create an array of all ones
Y=ones(n) Y=ones(m,n) Y = ones([m n]) Y =ones(d1,d2,d3...) Y = ones([d1 d2 d3...]) Y =ones(size(A))
Y = ones(n)
returns an n-by-n matrix of 1s. An error message appears if n is not a scalar.
Y = ones(m,n) or Y = ones([m n])
returns an m-by-n matrix of ones.
Y = ones(d1,d2,d3...) or Y = ones([d1 d2 d3...])
returns an array of 1s with dimensions d1-by-d2-by-d3-by-....
Y = ones(size(A))
returns an array of 1s that is the same size as A.
eye Identity matrix
rand Uniformly distributed random numbers and arrays
randn Normally distributed random numbers and arrays
zeros Create an array of all zeros
