Inverse matrix5/18/2023 The task manager shows that the memory usage at the time of error is 1GB. I have a 8GB memory(in a 64bit system), but I don't think I am making use of all of this memory space. It is actually the observation matrix, X, and I am trying to calculate ( X T X) -1 ![]() As UmNyobe suggested, this is not a square matrix. I should correct the size of the matrix to 21500x21500. Can there be any way to overcome this situation? So far I have tried Eigen and Armadillo libraries but both failed at initialization stage, saying that there is not enough memory. ![]() I am trying to calculate inverse of a very large matrix (11300x21500) in C++.
