Boolean Dirty { get; set; }
Becomes true after any of the properties have changed.
Returns: Boolean
Remarks:
When any of the TMtxOptimization properties changes, this property is automatically set to true. If Dew.Math.TMtxOptimization.AutoUpdate and Dirty are both true then the Dew.Math.TMtxOptimization.Recalculate method will be called automatically.
