A Graphical User Interface for multivariate nonlinear optimization

The code, nonlinopt_gui.m, presents a user friendly graphical user interface (GUI) to numerically find the optimal values of up to 10 coefficients in a nonlinear algebraic equation. As written it is intended to be optimize fitting parameters in a theoretical function to experimental data. It is extremely simple to use and is self-explanatory once the files are downloaded.

Installation instructions:

  1. Create a directory in your personal disk space called, for example, nonlinopt_gui
  2. Download the file nonlinopt_gui.zip to that directory
  3. Use WinZIP to extract the MATLAB files from the zipped file into the directory

Operation instructions:

  1. Open MATLAB
  2. Change directories to the directory where you extracted the files, by typing at the command line prompt
    cd z:\my_directory\nonlinopt_gui
  3. At the MATLAB command line prompt, type nonlinopt_gui
  4. The rest is self-explanatory
