I have written a matlab programme that provides graphical outputs from an input dataset to analyse a 'learning curve'. The inputs are two columns, the first is the ordinal number of repetitions (1, 2, etc), and the second column is the corresponding outcome (e.g. time taken to do an operation). The outputs are graphs that fit lines and line segments to the data to describe the trend in the 'learning curve'. I want to make this freely available for all researchers to use by inputting their data (e.g. in an uploaded .txt file in the appropriate format) and for the website to produce the output result.
