List of det() Examples

Examples of det()

Jama.Matrix.det()
Matrix determinant @return determinant
com.nr.la.Bandec.det()
Using the stored decomposition, return the determinant of the matrix A. @return
com.nr.la.LUdcmp.det()
Using the stored LU decomposition, return the determinant of the matrix A. @return
com.numb3r3.common.math.Matrix.det()
de.lmu.ifi.dbs.elki.math.linearalgebra.Matrix.det()
Matrix determinant @return determinant
edu.gmu.seor.prognos.unbbayesplugin.cps.Jama.Matrix.det()
Matrix determinant @return determinant
org.jamesii.core.math.Matrix.det()
Calculates the determinant value of the matrix. This is currently done with Laplacian expansion by minors which can be slow on large matrices.
TODO: Laplacian expansion is horribly slow for large (> 6×6) matrices. Better to use Gaussian elimination here. @return The determinant of the matrix @exception MatrixException if the matrix is not square

Examples of org.jamesii.core.math.Matrix.det()


    m = new Matrix(new double[][] { { 1, 2, 0 }, { 4, 0, 8 }, { 1, 2, 2 } });
    assertEquals(-16.0, m.det(), 0.000001);


    m = new Matrix(0, 0);
    assertEquals(1.0, m.det(), 0.000001);


    m = new Matrix(1, 1);
    m.setElement(0, 0, 42.23);
    assertEquals(42.23, m.det(), 0.000001);
