Re: [Scilab-users] range of colon
Samuel, Really?: --> x = rand(3,4,2); --> N= 5; --> siz = size(x); --> a = repmat(0,[N, siz(2:$)]); // Create array of 0's whose columns have length N --> a(1:siz(1), :) = x Submatrix incorrectly defined. It worked for size (8,1,3). It shouldn't work either, but somehow it does... Why not using resize_matrix()? Thanks! It is exactjy what I needed, only I was not aware of its existence!

[Scilab-users] range of colon
Dear all, I need to zero-pad the columns of an N-D array x to a length N. I've found the following solution: siz = size(x); a = repmat(0,[N, siz(2:$)]); // Create array of 0's whose columns have length N // and the remaining dimensions are the same as in x a(1:siz(1), :) = x; // Replace non-padding 0's by x This seems to work. However, I'm concerned about the use of the last : as a replacemant for all the remaining dimensions, since I couldn't find it documented. Is it an intended behviour?
