[Rd] feature request: enhance solve function with a symmetric option for faster operation for symmetric matrix

2005-06-08 Thread Jason Liao
Dear R developers, Recently I have a simulation program that needs to solve a large number of linear regression A x = b, where A is symmetric and constantly chnages. I found that the solve function is considerably less efficient than solve_symmetric = function(A, B) {
