    Fortran Bounded Least Square


    I have IMSL 7.1 on visual Intel FORTRAN.
    I have a complicated function to fit and the fitted parameters need to be always positive (constrained).
    The subroutine I currently use is UNLSF.

    Is there a subroutine in FORTRAN that can constrain the parameters? While looking the IMSL document, I see there is imsl_f_bounded_least_squares in C.
    Is there a similar subroutine in FORTRAN?

    Thank you
