Constrain regression coefficients to be equal

Hi guys,

I'm working on a code where I want to compare multiple regression models, one completely free, and one where the regression coefficients of the IV's are constrained to be equal.

In R (lavaan package) I would be able to constrain them like this -- Dependent ~ coef * Independent1 + coef * Independent2 (just for reference)

How can I do this in Matlab?

Make a new variable with

IndependentSum = Independent1 + Independent2;

and then fit the model with

Dependent~IndependentSum
