Toeplitz matrix
toeplitz can be used with empty matrices in Scilab but not in Matlab.
If c is complex, use mtlb_toeplitz in Scilab to have the same result than Matlab. Else if c is not a scalar or a vector, use mtlb_toeplitz in Scilab to have the same result than Matlab.
If c and r are not scalars or vectors or if c(1,1)<>r(1,1), use: mtlb_toeplitz in Scilab to have the same result than Matlab.
