I've been trying to create a matrix using the sparse matrix command:

M=sparse(IndR,IndC,KP,S,S,4);

Where IndR, IndC and KP are vectors of size (4*S) times 1. S is about 700,000.

I get the following error when running the command:

??? Error using ==> sparse Index exceeds matrix dimensions.

I double checked and IndR and IndC only take values in the range 1:1:S. Any clues of what might be going on? Thanks!
