clolesky_row
- Write twoMatlab functions L=clolesky_row(A) and L=clolesky_col(A) that compute the Cholesky factor L of a Symetric Positive De… nite (SPD) matrix A = LLT , acessing A by row and by column respectively.
pcg
- PCG Preconditioned Conjugate Gradients Method is a replacement of the standard built-in PCG code. Two new options are implemented: flex and null . The flex option changes the standard PCG algorithm into the flexible one. It allows using sophisticated
