CONSTRAINED FUNCTIONS Command (NLR command)
The optional CONSTRAINED
FUNCTIONS
command signifies the beginning of the constrained
functions program, which specifies nonlinear constraints. The constrained
functions program is specified after the model program and the derivatives
program (when used). It can only be used with, and must precede, the CNLR
command. See the topic BOUNDS Subcommand (NLR command) for more information.
Example
MODEL PROGRAM A=.5 B=1.6.
COMPUTE PRED=A*SPEED**B.
CONSTRAINED FUNCTIONS.
COMPUTE CF=A-EXP(B).
CNLR STOP
