Donald, regarding your new "Answer", you can do it like this: Use a for loop to calculate the elements o. for the maximum value in N. first=second; %Each term must by iterated upwards by an index of one. I am not sure why you create a table and turn it into an array afterwards. But I have a spreadsheet, and there are two columns of interest: one is labeled x_coord and the other is labeled y_coord. otherwise that's what i would have used too. I need to iterate through every element in an n-dimensional matrix in MATLAB. We can easily declare the 2D array in Matlab as follows. Also, you should be able to do Linear Indexing as described here. Edit: There is no shortest path between any pair of vertices , which form part of a negative cycle, because path-lengths from to can be arbitrarily small (negative). *L_C); L_series=50*(1/(3*10^(8)))*sqrt(epsilon_re).
