# LMEDenseLyapunov

Computes the solution of a dense continuous-time Lyapunov equation.

## Synopsis

    #include "slepclme.h"
    PetscErrorCode LMEDenseLyapunov(LME lme,PetscInt m,PetscScalar A[],PetscInt lda,PetscScalar B[],PetscInt ldb,PetscScalar X[],PetscInt ldx)

Logically Collective

## Input Parameters

- lme - the linear matrix equation solver context

- m - number of rows and columns of `A`

- A - coefficient matrix

- lda - leading dimension of `A`

- B - right-hand side matrix

- ldb - leading dimension of `B`

- ldx - leading dimension of `X`

## Output Parameter

- X - the solution

## Note

The Lyapunov equation has the form \(AX + XA^* = -B\), where all are \(m\times m\) matrices, and \(B\) is symmetric.
