Memory usage of a function

Question

0 个投票

I am trying to measure the memory usage of a function. I would like to compare the memory requirements for different methods of solving a linear system of equations. I am looking for a way of measuring it like this:

N = 100;
A = rand(N, N);
b = rand(N, 1);
mem1 = memory(sol = A \ b);
mem2 = memory(sol = sparse(A) \ b);

N = 100;
A = rand(N, N);
b = rand(N, 1);
mem1 = A \ b ; 
mem2 = sparse(A) \ b ;
whos mem1 mem2

  mem1      100x1               800  double              
  mem2      100x1               800  double
