zeros (Matlab function)
Create an array of all zeros
If A is a scalar, then Matlab returns a A*A matrix of zeros but in Scilab you get a 1, use zeros(A,A) to get the same matrix B. If A is a row 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.
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.
