measurement_vec_fit

Workspace.measurement_vec_fit: Vector

As measurement_vec, but fitted to the model.

This must often be the same size as measurement_sensor.

See measurement_vec for more details. In that notation, and in the notation of oemCalc(), \(\vec{y}_f \approx \vec{y} - \epsilon\). Or at least this should be the case depending on how good of a fit of \(\vec{x}\) has been produced and if the measurement can be understood properly.

Tip

It is often useful to present \(\vec{y} - \vec{y}_\epsilon\) and \(\vec{y}_f - \vec{y}_\epsilon\) instead of \(\vec{y}_f\) and \(\vec{y}\) directly. This removes the known measurement error from both the data and the fit, showing the physical signal from the target rather than known sensor noise.

This workspace variable belongs to forward calculations and state mapping. oemCalc() and oemCalcReduced() return their result in oem.measurement_vec_fit; they do not replace this independent workspace variable.
