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 XP systems. MATLAB for Mac OS supports US English only on Japanese language Mac OS systems. For more
information, contact The MathWorks, Inc.
Create a document in MATLAB

2. To specify the attributes of the new document, enter one of the following:
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.
