Examples of net.algart.math.functions.LinearOperator

net.algart.math.functions.LinearOperator

Linear operator (affine transformation): O f(x) = f(Ax + b), where the numeric n x n matrix A and the n-dimensional vector b are parameters of the transformation. (It is a particular case of the {@link ProjectiveOperator projective transformation}, when c vector is zero and d number is 1.0.) All calculations in all methods are performed in strictfp mode, so the results are absolutely identical on all platforms.

This class is immutable and thread-safe: there are no ways to modify settings of the created instance.
