any one know the code for doing normal vectors, binomials and curvature on MATLAB?

ive googled it, and didnt find much. There are usually example for how to enter this kind of stuff into Wolfram, but dint find anything.

thnx guys!

Normal vector can be represented as: grad(F)/norm(F)

or do it paper wise... 9.3 in textbook thers an example that shows u how...
T = r'/|r'|
N = T'/|T'|
B = T x N
