EvaluationMonitor

EvaluationMonitor
is an option for various numerical computation and plotting functions that gives an expression to evaluate whenever functions derived from the input are evaluated numerically.

DetailsDetails

  • The option setting is normally given as EvaluationMonitor:>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. »
