  com.numericalmethod.suanshu.vector.doubles.IsVector

public class IsVector
extends java.lang.Object

This class collects the utility functions to validate input arguments for vector operations.

Nested Class Summary

static class	IsVector.SizeMismatch This exception should be thrown when a vector operation is performed on two vectors with different sizes.
static class	IsVector.VectorAccessException This exception should be thrown if any invalid access to a Vector instance is detected.

Method Summary

static void	equalSize(Vector v1, Vector v2) Check if the input vectors are of the same size.
static void	validIndex(Vector v, int index) Check if the input index is a valid index Vector v.

Method Detail

equalSize

public static void equalSize(Vector v1,
                             Vector v2)

Check if the input vectors are of the same size.

Parameters:

v1 - a vector

v2 - a vector

Throws:

IsVector.SizeMismatch - if sizes do not match

validIndex

public static void validIndex(Vector v,
                              int index)

Check if the input index is a valid index Vector v.

Parameters:

v - a vector

index - the input index

Throws:

IsVector.VectorAccessException - if the index is invalid
