StepMonitor

StepMonitor
is an option for iterative numerical computation functions that gives an expression to evaluate whenever a step is taken by the numerical method used.

MORE INFORMATION

The option setting is normally given as StepMonitor:>expr.

The :> is used instead of -> to avoid expr being immediately evaluated.

Whenever expr is evaluated, all variables in the numerical computation are assigned their current values.

Block[{var₁=val₁, ...}, expr] is effectively used.

Basic Examples (3)

Monitor steps taken for a numerical minimization with FindMinimum:

In[1]:=

Out[1]=

Count steps:

In[1]:=

Out[1]=

Use Reap and Sow to collect step data:

In[1]:=

Out[1]=

Show steps on a plot of the function:

In[2]:=

Out[2]=
