This Hyperterminal application demonstrates the usage of the "FPU_Matrix_Driver.spin" object. This driver "expands" the matrix operation command set of uM-FPU v3.1 and provides the user a simple interface for calculations with vectors and matrices in SPIN programs. Beside basic matrix algebra, inversion, eigen-decomposition, sigular value decomposition (all up to 11-by-11), a minimal set of vector and float operations and float random number generation is supported by the driver.
