NMathFunctionsExpm(FloatComplexMatrix) Method

Computes the matrix exponential, e^A, of a given square matrix.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public static FloatComplexMatrix Expm(
	FloatComplexMatrix A
)

Public Shared Function Expm ( 
	A As FloatComplexMatrix
) As FloatComplexMatrix

public:
static FloatComplexMatrix^ Expm(
	FloatComplexMatrix^ A
)

static member Expm : 
        A : FloatComplexMatrix -> FloatComplexMatrix

Parameters

A FloatComplexMatrix: A square matrix.

Return Value

FloatComplexMatrix
A matrix F such that

Copy

F = exp(A)

Exceptions

Exception	Condition
MatrixNotSquareException	Thrown if the given matrix is not square.

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.
