true - Logical 1 (true)

Syntax

true
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.

Note   The size inputs m, n, p, ... should be nonnegative integers. Negative integers are treated as 0.

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)).
