Hello, I would like to perform some computations using MATLAB, these computations will consist in saving some large matrices at the end, so I would like to know how can I avoid having out of memory issue by preconditioning the matrices size at the beginning, i.e if a matrix with size let say 8000 x 8000 will generate out of memory, I could decrease the size before starting the calculations , which means I would like to know if there is a way to define a threshold size that doesn't produce a problem and in the meanwhile be large enough for my computations. Thank you!
