About Photoshop and MATLAB (Photoshop Extended)
MATLAB is a high-level technical computing language and interactive environment for algorithm development, data
visualization, data analysis, and numeric computation. With Photoshop Extended you can view MATLAB image-
processing results in Photoshop, and combine MATLAB commands with Photoshop image-editing features.
Once you connect to Photoshop from MATLAB, typing commands into the MATLAB command prompt performs
operations in Photoshop. You can run MATLAB algorithms and view the results in your image in Photoshop.
Note: Communication between Photoshop and MATLAB uses the Photoshop JavaScript interface and the MATLAB
library interface.
