Hi! Please consider the following:
1. X[501x1]
2. Y[501x1]
I am trying to use the polyfit block simulink. After setting the Order for 8, the last 4 values are always zero. similarly, for order 7, last 3 values are always zero and so on until 5, where i get no zeros. Please advise whether i am using the system in-correctly or my understanding is flawed??

Did you try double-clicking the Display block and changing the Format options? The default is "short", which may not show the smaller higher-order values.
