comment Gradient method
This question appears to be off-topic because it is not about the software program Mathematica. The poster asks for C++ code and for his work to be done for him. He may wish to post something to StackOverflow that sounds less like a demand, but I won't be migrating this in its current form.

comment Interpolation impossible for ListPlot with Missing?
Have you tried Null instead of Missing[]? I'm not near a computer with Mathematica to check, but this works for me in other contexts. But you will probably still need to index the data.

comment Programming paradigm change
Folks, these are all great solutions, but I do think beginning users would benefit from a bit of explanation of how your code works and why you chose to write it that way.

comment Eigenvectors for a large symbolic matrix
@Somayeh - have you tried just getting rid of the //MatrixForm command. That makes the head of Matrix into MatrixForm instead of List, which is what you need.

Your code is giving me errors. What sort of input are you expecting for Ngamm? I'm guessing positive integers, but it's not clear.
