Highlights from
GUI for Resistance Calculations

from GUI for Resistance Calculations by Imtiaz Hussain
Its a very simple GUI to calculate Resistance of a four band resistor from color codes.

colorcoding(varargin)
function varargout = colorcoding(varargin)
% COLORCODING M-file for colorcoding.fig
%      COLORCODING, by itself, creates a new COLORCODING or raises the existing
%      singleton*.
%
%      H = COLORCODING returns the handle to a new COLORCODING or the handle to
%      the existing singleton*.
%
%      COLORCODING('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in COLORCODING.M with the given input arguments.
%
%      COLORCODING('Property','Value',...) creates a new COLORCODING or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before colorcoding_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to colorcoding_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
