G0121: Matrix not positive definite [procs, line 140]2 Answers
0
This error means that on line 140 of the file named procs, your program is passing a matrix that is not positive definite to a GAUSS function that requires a positive definite matrix.
This most commonly occurs when a program passes a matrix that is not positive definite to the GAUSS function invpd. invpd calculates the inverse of a positive definite matrix.
