lsqlin with more than one set of data

I have two sets of data such that y1 = A1*x and y2 = A2*x

I can find x with use of lsqlin: x = lsqlin(A1,y1)

or

x = lsqlin(A2,y2)

But since x is the same in both cases, is there a way to find x when simultaniously optimizing case 1 and case 2? y1 and y2 are functions of time with different shape and no overlapping sample points.

I too have the same problem...did you get to a solution???

[Torsten]

[y1;y2] = [A1;A2]*x

So define y=[y1;y2] and L=[A1;A2] in lsqlin.

Best wishes

Have a look at this, this might help you.
