# True

Array of all logical 1 (true)

### true

• It returns logical 1.

### true(n)

• n should be non-negative integer.
• It returns an n-by-n matrix containing all logical 1.
• If n is not positive, it returns an empty array.
• If n is not integer, n would be rounded towards zero.
• It does not accept ±nan, or ±inf as its argument.

### true(s1, s2, ..., sn)

• s1, s2, ..., sn should be non-negative integers.
• It returns an array of lengths s1, s2, ..., sn that contains all logical 1.
• If any of s1, s2, ..., sn is not positive, it returns an empty matrix.
• Non-integer s1, s2, ..., sn would be rounded towards zero.

### true(sizeVec)

• It returns an array of size specified by the vector sizeVec. The array contains all logical 1.
• If any element of sizeVec is not positive, it returns an empty matrix. Non-integer element of sizeVec would be rounded towards zero.
