Constructor Detail

NonuniformPreparator

protected NonuniformPreparator(SimpleMesh mesh,
                               int order)

Constructs preparator of the required order.

Parameters:

mesh - a mesh

order - a difference order

Method Detail

calculateA

public void calculateA(SymBandedMatrix a)

Calculates the symmetric banded Laurent matrix for nonuniform mesh. The matrix size should be equal to the rows number of the finite differences matrix. The width of matrix half-band should be not less than the degree of the finite difference matrix.

Overrides:

calculateA in class MatrixPreparator

Parameters:

a - a matrix to store the result.
