### pbtrf

**Thu Jul 03, 2014 9:12 pm**pbtrf is available in the latest CULA Dense. That function computes the Cholesky factorization of a symmetric/Hermitian positive definite band matrix. However, I did not see pbtrs available, which is the function for solving AX=B using the Cholesky factorization provided by pbtrf. How does one use the result of pbtrf to solve AX=B in CULA Dense?
