Signal Processing Toolbox is a collection of industry-standard algorithms for analog and digital signal processing. The Signal Processing Toolbox also provides graphical user Interfaces for interactive design and analysis and command-line functions for advanced Algorithm development.
Most toolbox functions are implemented in the open MATLAB language. This means that you can inspect the algorithms, modify the source code, and create your own custom functions. You can use the toolbox for applications such as speech and audio processing, wired and wireless communications, financial modeling and analysis, and medical imaging and instrumentation.
