Im new to C... but I need to know how to do matrix multiplication, transpose, etc with C. Are there any good website for people like me?

I suggest looking into the math.h library. Havnīt had experience with these functions myself. Look in: http://www.cas.mcmaster.ca/~eng1d04/20022003/tm1/slides/VectAndMat.htm Otherwise, write them yourself, transpose isnīt hard to do with a pen and paper so it shouldnīt be hard to write as a function in C, if it isnīt already one which i would be supried if there wasnīt. Hope this help a bit on the way. Finaly: tip search in google: +"matrix" +"math.h"

G'day, Matrix manipulation is fun for 2x2 or even 3x3, but after that it is tedious. If the solutions are simple then fine, but most engineering solutions require numerical analysis (Guass-Siedel, Newton Rhaphson etc)and the key to the solution is the algorithm- not the language. If you can understand the algorithm (as azidstar has hinted at), then you can write the code. Another path is to look into the Pascal/ Algol texts, because they were very good at that in the 70's and you just need to convert them to C. regards, Elric
