All Known Subinterfaces:

GenMinRes.Norm

Enclosing class:

GenMinRes

public static interface GenMinRes.VectorProducts

Public interface for the user supplied function to the GenMinRes object used for the inner product when the Gram-Schmidt implementation is used.

Method Summary

double

innerproduct(double[] x, double[] y) Used to compute the inner product of 2 vectors for the Gram-Schmidt implementation.

Method Detail

innerproduct

double innerproduct(double[] x,
                    double[] y)

Used to compute the inner product of 2 vectors for the Gram-Schmidt implementation. If this function is not implemented, the dot product is used for the inner product.

Parameters:

x - first input double vector which is to take part in the inner product.

y - second input double vector which is to take part in the inner product.

Returns:

a double, the value of the inner product of x and y.
