Please explain in step and in Matlab code. Thank you.

5. (15 points) Write a m-file that does the following: a) use for loops to create the square matrix G, whose elements are given by Skl k+vi Vkl b) construct the transpose GT, c) compute the product GGT, and d) the trace of GGT. The trace of a matrix is defined as tr G=Li Jii, i.e. the sum of all elements along the main diagonal. The only parameter is the size, n, of the square matrix G. Test it for n = 10 and n = 100
