MATLAB is a popular analysis tool for researchers and scientists in engineering and the physical sciences. It is an established tool with astounding functionality. Unfortunately, it has a steep learning curve, can be cumbersome for simple tasks, and is expensive to purchase.
MATLAB 7 is available on the computers in the lab, along with a set of unsupported graphical fitting tools.
Fitting Tool for MATLAB 7.0 and above
Manual for data analysis tools
To check if the fitting tools are installed on the lab computer you are using, first open MATLAB by double clicking on the MATLAB icon on the desktop. Once MATLAB opens, type "databrowser" (sans quotes) into the command window. If an error occurs, i.e. "??? Undefined function or variable", the fitting tools are missing. (Please let the Lab Coordinator know if you find a computer without MATLAB or these tools.)
To install the tools, go to this page in your browser and double click the fitterR14 link above to download it. Then copy the contents of fitterR14 into the MATLAB (or other preferred) folder on the computer. Finally, you must go back into MATLAB, choose "Set Path ..." from the File Menu, click on "Add with Subfolders", select "MyDocuments\MATLAB" (or whatever location you downloaded the fitter), then Save and Close.
In case you have an older version of MATLAB, we also have a Fitting Tool for MATLAB 6.1 (Note: For MATLAB 6.1, only Manual sections 5.3,5.5 and the appendices are relevant.)
Note: The Advanced Lab no longer provides full support for these MatLab fitting tools. We will try to help you if we can, but our support is now primarily for Python.
