Simulink "Goodness" Block, Function to Coefficeint

Is there a Simulink block that will allow me to compare a calculated/predicted data point with an actual data point, then generate a coefficient to improve the calculation of future data points? Or, is there a MATLAB function that can be turned into said Simulink block?

With only one point, I don't know... but with a buffer of past points, this sounds like a cross-correlation:

Yes, you can use interpreted matlab function block or matlab function block

[Paul Huter]

I was hoping more for an example than a "yes, your can use a function".

[Azzi Abdelmalek]

Paul, I can't guess your hope, you did not ask for an example. I answered the second part of your question: is there a MATLAB function that can be turned into said Simulink block?. The first part is not clear for me. Read these links: interpreted matlab function and matlab function.

[Paul Huter]

Okay: if I have a calculated/predicted data point and a corresponding real data point - how can I generate some sort of coefficient in Simulink/MATLAB to improve the accuracy of the calculated/predicted point (or future points)?
