I seem to be getting quite different results when I use regress vs fitlm to do multivariate regression. Why?

I am looking for a function suggestion for the best suited for this functionality

‘The Coef_regress_ones matches with fitlm output, but with a large intercept value. But I already removed the mean value. I don't understand why.’
We still don’t have your data.
Removing the mean would not remove a trend (linearly-increasing baseline).

My pleasure.
Removing the mean does not necessarily mean that your signal does not have some sort of linear baseline trend.
Adding the ones vector allows the intercept to be estimated uniquely rather than being forced through zero. If you do not specify a ones column, the model forces a zero intercept.
