Potential Impact Recommended Actions

Optimization

Toolbox™

The option

PrecondBandWidth

has changed from

0 (preconditioned

conjugate gradients)

inf (Cho lesky

factorization). This

affects the large-scale

algorithms in

fsolve,

lsqcurvefit,and

lsqnonlin.

High-dimensional

problems may

exhibit slower

performance.

Changing

PrecondBandWidth to

a finite value using

optimset may improve

performance. Set

PrecondBandWidth to

0toobtainthesame

behavior as in previous

releases.

Optimization Toolbox Solvers fminco n,

fminimax,

fgoalattain,and

fseminf have a new

option:

TolConSQP.

This option exposes

a p arameter that

was fixed at

eps in

previous releases.

Some problems

might yield different

results from

previous releases.

Use

optimset to set

TolConSQP to eps to

obtain the previous

behavior.
