Not necessarily. It depends on the device. A matrix model assumes a perfectly 
additive device.

If the device _is_ perfectly additive, then it can be modelled _exactly_ by a 
matrix profile either (within the limits of device repeatability and 
measurement accuracy).

However, if the device is not additive, then a matrix model can't describe the 
device behaviour exactly, but can only approximate it (think of approximating a 
curve by a straight line - depending on the curve shape, the line will 
approximate the curve better or worse).

Best Regards,
