public class MatrixVariable extends DVariable implements MatrixVariableI
MatrixPartialDerivative
.
The derivatives are stored in a hashtable index by
the sorted names of derivatives.
i.e. d^2f/dxdy, and d^2f/dydx will both be indexed by {"x","y"}.
df/dx is indexed by {"x"}, d^2f/dx^2 is index by {"x","x"}.
Partial derivatives are calculated as required by the
findDerivative method.derivatives
Modifier and Type | Method and Description |
---|---|
protected PartialDerivative |
createDerivative(java.lang.String[] derivnames,
Node eqn) |
Dimensions |
getDimensions()
The dimension of the variable.
|
MatrixValueI |
getMValue()
returns the value, uses the Scaler type.
|
java.lang.Object |
getValue()
returns the value, unpacks Scalers so they just return its elements.
|
void |
print(PrintVisitor bpv) |
void |
setDimensions(Dimensions dims)
Sets the dimension of the variable.
|
void |
setMValue(MatrixValueI val)
Sets the value of the variable (matrix aware).
|
protected boolean |
setValueRaw(java.lang.Object val)
Sets the value of this variable.
