Matlab includes a constant as a default ..... is it possible to do a stepwise regression in Matlab without a constant? Thanks

It doesn't say so neither in stepwisefit nor in stepwise.
An example:

stepwise(ingredients,heat)

It does say: "stepwise automatically includes a constant term in all models. Do not enter a column of 1s directly into X."
