All of the commands that we've sued so far like plot, plotResiduals, and predict are methods for the LinearModel object. Any time that I'm working with one of the built in objects that ship with MATLAB my first plot is to inspect the full set of methods that ship with that object b = regress(y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X.To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. [b,bint] = regress(y,X) also returns a matrix bint of 95% confidence intervals for the coefficient estimates

Transforming Between Linear Model Representations. You can transform linear models between state-space and polynomial forms. You can also transform between frequency-response, state-space, and polynomial forms. If you used the System Identification app to estimate models, you must export the models to the MATLAB ® workspace before converting. While generally, in the context of fcMRI analyses, we are interested in simultaneously evaluating or testing thousands of individual measures (e.g. SBC maps containing one measure of interest at each voxel), in this section we will consider, for simplicity and illustration purposes, just a single measure, and proceed to manually define a General Linear Model and use it to test some simple. The equivalent code in MATLAB is pretty much the same as R.All you have to do is set up a data frame that has your variables, then use fitlm or LinearModel.fit to fit your linear model. fitlm is the more recent version of LinearModel.fit and is available from R2013b and onwards. It is suggested that you use fitlm if you have versions of MATLAB later than this
