Hello Tom, I recommmend Scilab. http://www.scilab.org/ Example A*x=B A=[1 2; 3 5] A = 1. 2. 3. 5. B=[1;2] B = 1. 2. x=A\B ans = - 1. 1. Alternative: x=inv(A)*B ans = - 1. 1. It has also a lot of functions for signal processing. Best regards, Helmut -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
