Method Details

setXComponentInternal

protected void setXComponentInternal(JepComponent comp)

Overrides:

setXComponentInternal in class DJep

addStandardDiffRules

public boolean addStandardDiffRules()

Description copied from class: DJep

Adds the standard set of differentiation rules. Corresponds to all standard functions in the Jep plus a few more.

 sin,cos,tan,asin,acos,atan,sinh,cosh,tanh,asinh,acosh,atanh
 sqrt,log,ln,abs,angle
 sum,im,re are handled separately.
 rand and mod currently un-handled

 Also adds rules for functions not in Jep function list:
        sec,cosec,cot,exp,pow,sgn 
 

Overrides:

addStandardDiffRules in class DJep

Returns:

false on error

calcDims

public void calcDims(Node node)
              throws ParseException

Calculates dimensions for a node.

Parameters:

node -

Throws:

ParseException

getMatrixFactory

public MatrixFactoryI getMatrixFactory()

getMfield

public MatrixFieldI getMfield()

getDimensionVisitor

public DimensionVisitor getDimensionVisitor()
