Method Details

checkMERepresentation

public static boolean checkMERepresentation(Matrix alpha,
 Matrix A,
 double prec)

Checks if the given vector and matrix define a valid matrix- exponential representation.

Parameters:

alpha - Initial vector of the matrix-exponential distribution to check

A - Matrix parameter of the matrix-exponential distribution to check

prec - Numerical precision. The default value is 1e-14.

Returns:

True, if the matrix is a square matrix, the vector and the matrix have the same size, the dominant eigenvalue is negative and real Note: This procedure does not check the positivity of the density! Call 'checkMEPositiveDensity' if it is needed, but keep in mind that it can be time-consuming, while this procedure is fast.
