You may refer to theExport Regression ModelStep of training a Linear Regression Model. This will store the variables containing the parameters into MATLAB Workspace. Information regarding coefficients andconstantwill be stored intrainedModel.LinearModel.Coefficientsfield in thetrainedModelvariable. This format is only valid if Linear Regression method is usedin the RegressionLearner App. Different kinds of parameters will come into picture if some other algorithm is used such asRegression Trees,Support Vector Machinesetc.
