Identification of SIMO system: poles for each transfer function different

Hey guys,

I'm trying to estimate system parameters of a SIMO system (1 input, 2 output) using function tfest(). I would expect a 2x1 transfer function matrix and both element share the same denominator and poles.

However, the result from tfest() gives me different denominator for each transfer function (apparently it estimated the two transfer functions individually). Is there a way to enforce a constraint on tfest() to make sure that the 2 transfer function have the same denominator?

I am having the same problem. Did you find the answer? Thanks.
