Method Detail

assertCountable

public static void assertCountable(SimpleMatrix A)

Checks to see if every element in A is countable. A doesn't have any element with a value of NaN or infinite.

Parameters:

A - Matrix

assertShape

public static void assertShape(SimpleMatrix A,
                               SimpleMatrix B)

Checks to see if A and B have the same shape.

Parameters:

A - Matrix

B - Matrix

assertEqualsUncountable

public static void assertEqualsUncountable(SimpleMatrix A,
                                           SimpleMatrix B,
                                           double tol)

Checks to see if each element in the matrix is within tolerance of each other:

The two matrices are identical with in tolerance if:
|a_ij - b_ij| ≤ tol

In addition if an element is NaN or infinite in one matrix it must be the same in the other.

Parameters:

A - Matrix A

B - Matrix B

tol - Tolerance

assertEquals

public static void assertEquals(SimpleMatrix A,
                                SimpleMatrix B,
                                double tol)

Checks to see if each element in the matrices are within tolerance of each other and countable:

The two matrices are identical with in tolerance if:
|a_ij - b_ij| ≤ tol

The test will fail if any element in either matrix is NaN or infinite.

Parameters:

A - Matrix A

B - Matrix B

tol - Tolerance
