MATLAB is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. With Photoshop 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.
Install Photoshop and MATLAB on your computer. Once you have installed Photoshop and MATLAB, you should verify the MATLAB integration.
Download and install the MATLAB plug-in package.
This package contains the MATLAB library and sample scripts for both English and Japanese.
Typing commands in the MATLAB command line lets you connect and disconnect to Photoshop, and generate pixels viewable in a Photoshop document.
For a list of all MATLAB Photoshop commands, browse the file psfunctionscat.html, available in the MATLAB folder in the directory where you installed Photoshop. Enter help (command name) at the MATLAB command prompt for a fuller description of each command, including syntax, arguments, and examples.
All MATLAB commands are supported for Japanese characters. MATLAB for Windows supports a Japanese language user interface on Japanese language Windows systems. MATLAB for macOS supports US English only on Japanese language macOS systems. For more information, contact The MathWorks, Inc.
To create a document using the default values, enter psnewdoc(). For information on default values, see below.
To create a document with a specific width and height, enter psnewdoc(W,H). The W and H values use the current units set in the Units & Rulers option in the Photoshop Preferences dialog box. Other document attributes are set to their default values.
Enter “undefined” as a string to skip input arguments. The default size for a new document is 504 x 360 pixels.
- To create a document and specify attributes, enter psnewdoc(W,H,R,N,M,F,A,B,P). For information on new document attributes, see below.
psnewdoc(10, 10, 72, 'hi', 'cmyk', 'transparent', 2.5, 16, 'U.S. Web Coated (SWOP) v2')
Specifies the width of the document using the current units from the Units & Rulers option in the Photoshop Preferences dialog box. The default width is 504 pixels.
