Multiple Linear Stepwise Regression

I'm trying to get MATLAB to do stepwise regression for me and I know there's some functions out there like stepwiselm and stepwiseglm which does this.
My dependent variable is Y.
My independdent variables are X1, X2, X3 etc.
The stepwiselm and stepwiseglm functions im MATLAB gives me a regression model such as
Y = Beta(1)X1*X2 + Beta(2)*X(1) + Beta(3)*X(2) + Beta(4)*X(3) + C
whereas I'm after
Y = Beta(1)*X(1) + Beta(2)*X(2) + Beta(3)*(X3) + C
Tried changing modelspec to constant and linear as well.
Any help would be much appreciated!

You could use the upper and lower parameters in the stepwiselm and stepwiseglm functions to specify the set of independent variable terms to be present in the model equation.

Hope this helps!
