ones (Matlab function)
Create an array of all ones
Note that in Matlab, A can contain complex values (in these cases, only real part of A is taken in account), what Scilab function do not tolerate.
// Scilab version B=ones(A)
Most differences stem from the use of ones in conjunction with size. In Scilab you do not need to use size:
// Scilab version A = [1 2 ; 3 4]; B = ones(A) B =[ 1 1 ; 1 1]
As a result, if A is a scalar, then Matlab will return a A*A matrix of ones but in Scilab you get a 1 (just because a scalar is a 1*1 matrix), so use ones(A,A) to get the same matrix B. If A is a vector, Scilab and Matlab give the same B. Finally, if A is a matrix, in Scilab, B will be a matrix having the same size as A whereas in Matlab, you get an error message.
