| Version | Published | Release Notes | Action |
|---|---|---|---|
| 1.0.8 | Added the following models:
|
||
| 1.0.7 | Updated the index of RMS, now base on the number of data points from the VLE data. |
||
| 1.0.6 | 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. |
||
| 1.0.5 | 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. |
||
| 1.0.4 | Update 2 on the Wilson, Van Laar and Margules Models |
||
| 1.0.3 | Updated the documentation for Wilson, Van Laar and Margules. |
||
| 1.0.2 | -Added a UNIQUAC model. All the models so far are still for isothermal conditions.
|
||
| 1.0.1 | The only data to be loaded are x1, y1 and P. |
||
| 1.0.0 |
