One of the most important features of the MATLAB environment is that it is extensible. MATLAB lets you create your own M-files to meet numeric computation needs for research, design, or engineering of signal processing systems. Simply copy the M-files provided with the Signal Processing Toolbox product and modify them as needed, or create new functions to expand the functionality of the toolbox.
A number of other MATLAB products expand and enhance the Signal Processing Toolbox product. These include:
Filter Design Toolbox — Toolbox for advanced filter design
Signal Processing Blockset™ — Product based on Simulink® for creating and analyzing signal processing models
Fixed-Point Toolbox — Toolbox for using fixed-point arithmetic
Filter Design HDL Coder — Toolbox for creating and exporting HDL code
Embedded IDE Link™ — Toolbox for working with embedded software on Texas Instruments™ DSPs
