Create scripts with code, output, and formatted text in a single executable document.
Added the following models:
Updated the index of RMS, now base on the number of data points from the VLE data.
Fixed the SSE function. In the past versions, the evaluation works as: SSE(SSE(function)) since lsqnonlin already evaluates the SSE of the function. This has been fixed in this update.
Syntax 2 using polyfit is now the open code instead of mvregress for margules.m and van laar.m so no need to download the statistics and machine learning toolbox.
Update 2 on the Wilson, Van Laar and Margules Models
Updated the documentation for Wilson, Van Laar and Margules.
-Added a UNIQUAC model. All the models so far are still for isothermal conditions.
The only data to be loaded are x1, y1 and P.
