I am taking Numerical methods for engineering. and it says that i have to write a user-defined Matlab function (M file) to calculate the 1 - norm of any matrix and infinity norm matrix.
it does not say anything in the book and i searched all over....
I really need codes for these. thanks for looking my question.

Give this a try:
help norm
After you read the text, you should know how to proceed.

If you implement a matrix norm using the code shown in "help norm", use "sum(X, 1)" instead of "sum(X)" to consider row vectors also.
