optimisationDigest

Prints the results of an optimisation and returns validity of optimum

Syntax

ISVALID = optimisationDigest(STRUCTOUT,STRUCTIN)

ISVALID = optimisationDigest(STRUCTOUT,STRUCTIN,FILENAME)

ISVALID = optimisationDigest(STRUCTOUT,STRUCTIN,[])

Description

ISVALID = optimisationDigest(STRUCTOUT, STRUCTIN) Prints digest to standard output, where STRUCTOUT is the output, and STRUCTIN the input, from OptionsMatlab. ISVALID is 1 where the optimum point returned by the optimisation does not violate the constraints or the design variable limits, otherwise ISVALID is 0.

ISVALID = optimisationDigest(STRUCTOUT,STRUCTIN,FILENAME) Prints direct to FILENAME

ISVALID = optimisationDigest(STRUCTOUT,STRUCTIN,[]) Suppresses digest output

Example

The output of optimisationDigest is illustrated by the following example:

>> input = createBeamStruct

>> results = OptionsMatlab(input)

>> isvalid = optimisationDigest(results,input)
