ones

Array of all ones

ones

• It returns 1.

ones(n)

• n should be non-negative integer.
• It returns an n-by-n matrix containing all ones.
• 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.

ones(s1,s2,...,sn)

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

ones(sizeVec)

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