MATLAB offers toolboxes that expand its capabilities to perform such tasks as plotting functions and algorithms, financial modeling and analysis, signal processing, technical computing, and image processing.

Photoshop integration with MATLAB was added in Photoshop CS3 Extended. This integration provides functions that allow pixels to be sent to Photoshop for manipulation, or brought into MATLAB for analysis and visualization. This capability was originally included for the benefit of professionals working in the scientific and engineering fields, but artists and designers have been taking advantage of its ability to analyze images for tasks such as generating custom color palette.
