What's this setting of MATLAB for(which is causing lots of troubles for lots of people)?

This setting in PATH:

D:\MATLAB\R2007b\bin\win32

Here is a fresh bad affect by this setting for me:

How does PATH environment affect my running executable from using msvcr90 to msvcr80?

And here's an issue reported by another guy:

What's that setting fo开发者_如何学Gor and why it's causing so many problems?

I'm not sure if you are talking about the PATH system environment variable or the MATLABPATH environment variable. If you mean the system environment variable, Andrew's answer seems to answer the question. Otherwise, here's some information about the MATLAB variable, in case you meant that:

The MATLABPATH variable in MATLAB tells MATLAB where to look for functions. It's analogous to the PATH system environment variable in both Windows and *nix systems (which is what Andrew was describing), but is only for the MATLAB environment.

For example, if you had a script called myScript.m stored in the C:\Users\me\Documents\MATLAB\ directory that defines the function myScript, you would be able to use your myScript function regardless of what directory you are currently working in in MATLAB.

You may modify your MATLABPATH by using the path, addpath, genpath, and other such functions.
