How do I obtain the linear intercept from each iteration using stepwisefit or stepwiselm?

I'm performing a multi-variate regression analysis on 4 predictor variables (X) and a response variable (y). I want to be able to force all 4 of the predictor variables into the regression analysis and obtain the intercept for this. I'm able to force all the predictor variables into the analysis using the Stepwisefit function, however the intercept is only output for the final iteration. Does anyone know how I could obtain the y intercept for each iteration using either of these functions?
