Fast Matrix for Java (fm4j) is a general-purpose matrix utility library for computing with dense matrices.

fm4j encapsulated different underlying implementations and select the optimal one in run-time depending on the size of the input matrix. Moreover, fm4j employs Java (Tm) Concurrency to take advantage of the computation power of multi-cor processors.
