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
  /BOUNDS CF LE 0.
