Optimization Toolbox

Converting Your Code to Version 2 Syntax

Most of the function names and calling sequences have changed in Version 2 to accommodate new functionality and to clarify the roles of the input and output variables.

As a result, if you want to use the new versions of these functions, you need to modify any code that currently uses the old function names and calling sequences.

This table lists the functions provided by the Optimization Toolbox and indicates the functions whose names changed in Version 2.

Old (Version 1.5) Name	New (Version 2) Name
attgoal	fgoalattain
conls	lsqlin
constr	fmincon
curvefit	lsqcurvefit
fmin	fminbnd
fmins	fminsearch
fminu	fminunc
fsolve	fsolve (name unchanged)
fzero	fzero (name unchanged)
leastsq	lsqnonlin
minimax	fminimax
nnls	lsqnonneg
lp	linprog
qp	quadprog
seminf	fseminf

This section

• Tells you how to override default parameter settings with the new optimset and optimget functions
• Explains the reasons for the new calling sequences and explains how to convert your code
• Provides a detailed example of rewriting a call to the constr function to call the new fmincon function instead

In addition to the information in this section, consult the M-file help for the new functions for more information about the arguments they take. For example, to see the help for fmincon, type

• help fmincon
