Version 3.2 of Model_Exporter was released in June, 2015. For general product information, see Model_Exporter_User_Guide.

NEW FEATURES / FIXES

• Add support for non-negative least squares CLS models IF outputting to m-file format (requires function be enabled as sub-functions are added to accomplish the NNLS calculation)
• Add support for approximate nearest neighbor distance via distancemetric option. This is an approximation of the NN distance, but is NOT exact.
• Add support for application of most preprocessing methods to MATRICES
  • Allows use of PLS, PCR, PCA, CLS, and PLSDA on x-block of MATRICES (not just vectors) with basically all supported preprocessing methods
• Add basic support for arithmetic on X-block (only - undo on y-block not supported)
• Change "prob" to "probs" in SVMDA so it matches PLSDA outputs
• Fix bug where placeholder variables were not removed from data if SavGol preprocessing was the one and only preprocessing method
• Fix bug which would lead to indexing error in SavGol preprocessing if variables at the END of the spectrum are excluded

Model Interpreter

• Allow input of matrix instead of just vectors (some methods support applying to matrix)
• Force numeric conversion to be done expecting period as decimal separator (resolves problems interpreting models on systems set to other numeric formats like in France)
• Move math steps into new MEMath object (simplifies code - exposes mathematical operations to caller)
