MatrixDifferentiationVisitor (Jep with extensions API )

java.lang.Object
- com.singularsys.jep.walkers.DoNothingVisitor
- - com.singularsys.jep.walkers.DeepCopyVisitor
  - - com.singularsys.extensions.djep.DifferentiationVisitor
    - - com.singularsys.extensions.matrixdiff.MatrixDifferentiationVisitor

All Implemented Interfaces:

JepComponent, ParserVisitor, java.io.Serializable
```
public class MatrixDifferentiationVisitor
extends DifferentiationVisitor
```
A DifferentationVisitor which knows about vectors and matrices. In particular it knows the derivative of a constant matrix is the zero matrix. It only works with the vector and matrix functions of a real variables and not the advanced case of functions of vector and matrix variables.
