| NMathFunctionsExpm(FloatComplexMatrix, Single) Method |
Computes the matrix exponential, e^A, of a given square matrix.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static FloatComplexMatrix Expm(
FloatComplexMatrix A,
float delta
)
Public Shared Function Expm (
A As FloatComplexMatrix,
delta As Single
) As FloatComplexMatrix
public:
static FloatComplexMatrix^ Expm(
FloatComplexMatrix^ A,
float delta
)
static member Expm :
A : FloatComplexMatrix *
delta : float32 -> FloatComplexMatrix
Parameters
- A FloatComplexMatrix
- A square matrix.
- delta Single
- Error tolerance.
Return Value
FloatComplexMatrixA matrix
F such that
where
E
is a matrix with
.
Exceptions Remarks This method uses a scaling and squaring method based upon Pade
approximation. Note this method raises the constant e to a matrix
power, which is different than Exp( FloatComplexMatrix A)
which exponentiates each element of a matrix independently.
