Hi.
In using your (great) program I encounered an annoying thing: I was unable to derivate a Matrix. Please add this feature if possible sice working with large matrixes is quite timeconsuming

Hello, Please look at the examples included in SMath Studio and the wiki page diff. If this is not what you need, please be more specific about the problem you would like to be solved. Regards, Radovan Edited by user 15 November 2009 03:54:03(UTC)

The thing I am trying to do is turn this: d/dx(x^2, x, x+1)
into (2x, 1, 1). but with bigger matrixes as well, not only vectors (or 1x3 matrix)

Try this, M(x)←mat(x^2;1-x;x;x^3+e^x;2;2)r←rows(M(x))c←cols(M(x))for(i;range(1;r);for(j;range(1;c);el(dM;i;j)←diff(el(M(x);i;j);x)))Mprime(x)←dMMprime(x)—mat(2*x;-1;1;3*x^2+e^x;2;2)Mprime(2)=mat(4;-1;1;19,3891;2;2)Try with a matrix function M(x) with more rows and columns.
