I am trying to develop a program and I am stuck on a few portions.
1. I need the program to calculate the gradient of a user entered function.
2. I need to multiply matricies which I think I know how to do but the matricies need to have variable dimensions depending on the number of variables in the user entered function.
3. I need to make the program transpose the matrix.
I have written one program ever and this seems somewhat complex to me, not the math the programming. any starting point for me would be really helpful.
thanks in advance.
