In Maintenance? Assure Access to Helpdesk, Updates and More!

Like most software packages, our PLS_Toolbox, Solo and other products come with a maintenance program. When you are “in maintenance” you have access to support through our helpdesk@eigenvector.com email address. And unlike the software support of many firms, our Helpdesk is monitored our software development staff team members including Scott, Donal, Lyle, Nate and Bob. This is the crew that is actually responsible for writing our software. So when you contact Helpdesk you’re actually talking to the people behind the code. That’s why our customers say our Helpdesk is actually helpful!

Of course most of our customers never need any help. So why should they purchase maintenance? Because we’re always improving our software, and when you are in maintenance you have access to all the improvements and new features. For instance, here are the highlights of what we’ve added in our major releases since October 2021:

Version 9.0 — Faster engine, modern Machine Learning methods

• Updated Solo engine to MATLAB R2020b for improved speed and graphics. Added Python-integrated methods including deep learning neural networks (ANNDL, ANNDLDA) and nonlinear pattern recognition (UMAP, t-SNE).

Version 9.1 — Parallel Computing, improvements to non-linear methods

• Parallel computing enabled to speed computation in many non-linear methods, improvements to ANNDL, ANNDL-DA, UMAP

Version 9.2 — Smarter classification and spectral filtering

• HMAC automated hierarchical model builder. Grey CLS with GLS and EPO filters for interference correction.

Version 9.3 — Temperature correction, interpretation and expanded classification

• Temperature-interpolated Classical Least Squares (CLSTI). Shapley values and sensitivity for nonlinear model interpretation (EVRISHAPLEY). Linear Discriminant Analysis (LDA).

Version 9.5 — Semi-automated model development

• Diviner: a high-throughput search engine that accelerates calibration model development by systematically exploring preprocessing and variable selection combinations.

Our next major release will be PLS_Toolbox/Solo version 9.6 which we plan to ship this summer. This version will include further improvements to Diviner plus the addition of lean chemometric methods and tools for working with volume fractions. We’ll also be building Solo with MATLAB R2024b which will assure continued compatibility with the latest Windows and MacOS operating systems. And for you PLS_Toolbox users stay tuned for news about compatibility with MATLAB R2026.

Happy (updated) modeling!
