      org.jscience.mathematics.vectors.Matrix<Float64>
          org.jscience.mathematics.vectors.Float64Matrix

All Implemented Interfaces:: java.io.Serializable, Realtime, Immutable, GroupAdditive<Matrix<Float64>>, Ring<Matrix<Float64>>, Structure<Matrix<Float64>>, VectorSpace<Matrix<Float64>,Float64>

public final class Float64Matrix
extends Matrix<Float64>
extends Matrix<Float64>

This class represents an optimized matrix implementation for 64 bits floating-point numbers.

Instances of this class can be created from Float64Vector, either as rows or columns if the matrix is transposed. For example:

        Float64Vector<Rational> column0 = Float64Vector.valueOf(...);
        Float64Vector<Rational> column1 = Float64Vector.valueOf(...);
        Float64Matrix<Rational> M = Float64Matrix.valueOf(column0, column1).transpose();
