The function invpd returns the inverse of a positive definite matrix. If the input to invpd is not positive definite, then you will get the error:
error G0121 : Matrix not positive definite
You need to look at the matrix _opfhess before it is passed into the function invpd. You can do this with by using the debugger or a print statement.
If the contents of _opfhess are missing values or a scalar error code, they will print out like this:
.
If you see this, you will need to trace back in the program and see what caused this.
