MATLAB Crashes with Segmentation Fault when Solving BICG Function with Sparse Matrices

Hello everyone, basically this happens no matter what is the size of the sparse matrix. I crease sparse matrix using sparse(i,j,s) function in Matlab. Then, when I try to use bicg function with the created sparse matrices( https://www.mathworks.com/help/matlab/ref/bicg.html ), matlab crashes because it runs out of memory. I cannot use full matrices because the size of the 3d matrices are too much (100x100x100). How can I solve this problem?

A 100-by-100-by-100 full matrix isn't that big.

A = ones(100, 100, 100);
whos A

  Name        Size                   Bytes  Class     Attributes

  A         100x100x100            8000000  double              

What does the following code show when called immediately before you try to create a sparse matrix that causes MATLAB to run out of memory?

rows = max(i)
cols = max(j)

My guess is that you have a much larger value in j than you think you do.
