Adding functions permanently to matlab
显示 更早的评论
I have many self developed functions in a folder called Finance (C:\Documents\MATLAB\Finance). I sthere a way to add these functions permanently to my matlab path so whenever i use a script this script would call them automatically?

Yes, look under File>Set Path. Add the directory Finance to the path. This should persist between sessions.

In MatLab R2018a, look under Home > ENVIRONMENT > Set Path

Yes. Use the path() or addpath() command in a file called startup.m, in the top-level MATLAB directory. For example, where is how I added a utilities directory (on a Mac):
path(path,genpath('/Users/thecyclist/Documents/MATLAB/utilities'));
That file is run at MATLAB start.

(Sorry to resurrect a very old thread...)
I know about path, pathtool, and the GUI approach suggested above to make functions available from the Command Prompt, and I realize any of those would work for functions located pretty much anywhere on the host.
Just curious: is there a conventional / standard / "best practices" location for parking such self-developed functions, as per the OP's question? Initially I thought about $MATLABROOT/toolbox/local, but that seems to contain exclusively Mathworks-provided scripts and text files.

This is a completely different question. Please don't resurrect an old question to ask a new one.
But do NOT put functions in the matlabroot directories. The toolbox directories are cached on startup, so any changes you make to your personal functions will not be seen.

John-
I asked here because I thought my query was directly relevant to the OP's question (modulo "how" vs. "where"). My apologies. I'll re-post this as a new question.
Thanks also for the info about caching at startup. I can easily imagine this would result in confusing/unexpected behavior if I were to edit any of those functions during a session, then fail to quit/restart. Cheers.
