Fillmissing function with movmean

I have a set of data with NaNs. So I filled the NaNs useing the fillmissing function. However, while the final array does not have NaNs in it, any mathematical computation performed on it returns NaN. What could be the problem?

Thanks

Operations involving NaN as one of the operands is one common way to get a NaN in the output, but it is not the only way. See Wikipedia for a list of other operations that can generate a NaN. If all your data is finite, likely you computed 0/0.

x = 0/0

x = NaN

There are more ways to generate a NaN if infinity gets involved (such as if your calculations overflow.)

[0*Inf, Inf-Inf, Inf/Inf, rem(Inf, 0)]

ans = 1×4

NaN NaN NaN NaN
