Documentation API of the 'cern.colt.matrix.doublealgo.Transform' Java class

Class Transform

  • All Implemented Interfaces:
    Serializable, Cloneable


    public class Transformextends PersistentObject
    Deprecated; Basic element-by-element transformations on DoubleMatrix1D and DoubleMatrix2D.All transformations modify the first argument matrix to hold the result of the transformation.Use idioms like result = mult(matrix.copy(),5) to leave source matrices unaffected.

    If your favourite transformation is not provided by this class, consider using method assign in combination with prefabricated function objects of Functions,using idioms like

    cern.jet.math.Functions F = cern.jet.math.Functions.functions; // aliasmatrix.assign(F.square);matrix.assign(F.sqrt);matrix.assign(F.sin);matrix.assign(F.log);matrix.assign(F.log(b));matrix.assign(otherMatrix, F.min);matrix.assign(otherMatrix, F.max);
    Here are some other examples.

    Implementation: Performance optimized for medium to very large matrices.In fact, there is now nomore a performance advantage in using this class; The assign (transform) methods directly defined on matrices are now just as fast.Thus, this class will soon be removed altogether.
