Dear All,
Could you help me in finding a tricky method (other than the below ) for creating a temporary matrix with a large size?
Method already tried;
1. Allocating the maximum workspace for matrix creation in MATLAB.
2. Using the function sparse
3. Using single precision
4. Increasing space using page file
Thank you! WIll be highly appreciated your suggestions :)
One trick with Matlab is that it processes column vectors much faster then row vectors. I believe that newer versions of Matlab save one-dimensional arrays as column vector anyways. I would vectorize sparse matrix so that you have two columns array at the end: one with the values and the other with vectorized indices.
Did you try "Tall Arrays"?

Well what I wrote is the same: if you chop the vectorized sparse matrix you woun't loose the index integrity anyways.
