  true(n)
  true(m,n)
  true(m,n,p,...)
  true(size(A))
  

Description

true is shorthand for logical(1).

true(n) is an n-by-n matrix of logical ones.

true(m,n) or true([m,n]) is an m-by-n matrix of logical ones.

true(m,n,p,...) or true([m n p ...]) is an m-by-n-by-p-by-... array of logical ones.

true(size(A)) is an array of logical ones that is the same size as array A.

Remarks

true(n) is much faster and more memory efficient than logical(ones(n)).
