Hi,
I am using Cholesky decomposition library function to find the inverse of a positive definite complex matrix (of size 12 x 12). However the output "X" from the function is a vector of only 12 values. Can you please advice how to get the complete 12 x 12 inverse output values from these library functions? From my understanding of the algorithm, I am giving input vector b as {1,0,0,0,0,0,0,0,0,0,0,0}. Is this vector size and values correct?
I am using the following functions to compute the inverse of a 12 x 12 positive definite complex matrix:
1. DSPF_sp_cholesky_cmplx(1, 12, A, L);
2. DSPF_sp_cholesky_solver_cmplx(12, L, Y, b,inv_A);
where A is the input matrix, L is the generated Lower triangular matrix, Y is the intermediate values computed, b is an input vector, inv_A is an output vector.
Thanks!
