Python _matrix_derivative Examples

Example #1

File: trace.py Project: cosmosZhou/sagemath

 def _eval_derivative(self, v):
     from sympy.matrices.expressions.matexpr import _matrix_derivative
     return _matrix_derivative(self, v)

Example #2

File: array_derivatives.py Project: liyanxp/NmercialExperiment

 def _call_derive_default(expr, v):  # type: (Expr, Expr) -> Optional[Expr]
     if expr.has(v):
         return _matrix_derivative(expr, v)
     else:
         return None

Example #3

 def _call_derive_scalar_by_matexpr(expr,
                                    v):  # type: (Expr, MatrixExpr) -> Expr
     if expr.has(v):
         return _matrix_derivative(expr, v)
     else:
         return ZeroMatrix(*v.shape)

Example #4
