Method Detail

isEquivalent

public static boolean isEquivalent(ReshapeMatrix64F a,
                   ReshapeMatrix64F b,
                   double tol)

isIdentity

public static boolean isIdentity(ReshapeMatrix64F a,
                 double tol)

Returns true if the provided matrix is has a value of 1 along the diagonal elements and zero along all the other elements.

Parameters:

a - Matrix being inspected.

tol - How close to zero or one each element needs to be.

Returns:

If it is within tolerance to an identity matrix.

isEquivalentTriangle

public static boolean isEquivalentTriangle(boolean upper,
                           ReshapeMatrix64F a,
                           ReshapeMatrix64F b,
                           double tol)

copy

public static void copy(ReshapeMatrix64F from,
        ReshapeMatrix64F to)

setRandom

public static void setRandom(ReshapeMatrix64F a,
             double min,
             double max,
             Random rand)
