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.

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.

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.
