Method Detail

getDeterminant

public java.lang.String getDeterminant()
                                throws java.lang.Exception

The determinant is computed. This is a very time consuming process. If possible, the matrix should be set to numerical (setNumerical ()).

Returns:

Determinant of the (suqare) matrix.

Throws:

java.lang.Exception

setComponents

public void setComponents(java.lang.String[][] components)
                   throws java.lang.Exception

Overrides:

setComponents in class Matrix

Throws:

java.lang.Exception

getDeterminant

public static double getDeterminant(double[][] b)

Parameters:

b - Array with numerical entries.

Returns:

Determinant of the array.

getDeterminant

public static java.lang.String getDeterminant(java.lang.String[][] b,
                              boolean is_numerical)
                                       throws java.lang.Exception

Parameters:

b - String-valued array.

is_numerical - 'true' if all entries are numerical, 'false' else.

Returns:

Determinant of the array.

Throws:

java.lang.Exception
