Method Detail

assertCountable

public static void assertCountable(Matrix64F 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(Matrix64F A,
                               Matrix64F B)

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

Parameters:

A - Matrix

B - Matrix

assertShape

public static void assertShape(Matrix64F A,
                               int numRows,
                               int numCols)

Checks to see if the matrix has the specified number of rows and columns.

Parameters:

A - Matrix

numRows - expected number of rows in the matrix

numCols - expected number of columns in the matrix

assertEqualsUncountable

public static void assertEqualsUncountable(Matrix64F A,
                                           Matrix64F 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(Matrix64F A,
                                Matrix64F 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

assertEqualsTrans

public static void assertEqualsTrans(Matrix64F A,
                                     Matrix64F B,
                                     double tol)

Checks to see if the transpose of B is equal to A and countable:

|a_ij - b_ji| ≤ tol

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

Parameters:

A - Matrix A

B - Matrix B

tol - Tolerance
