But one of wonderful things about glm() is that it is so flexible. The example begins with a procedure to export the CAD assembly. The answer is: No! An FMU is simply a compressed archive. In statistics, ordinal regression (also called "ordinal classification") is a type of regression analysis used for predicting an ordinal variable, i. You use fitlm to train a linear regression model, so you provide it the predictors as well as the responses. A model including all first-order effects and interactions up to the nth order, where n is given by ( )^n. System & matlab. And since Deep Learning Toolbox supports the ONNX model format, you can import models, leverage MATLAB for tasks like visualizing and optimizing your network, and then export your model for use in other deep learning frameworks. Suppose you export the trained model to MATLAB Workspace based on the instructions in Export Model to Workspace, with the name trainedModel.
