Hi,
Is there a way to take the moving avereage of a 2D matric over a time interval. I have attached what I tryed bellow with the error message shown after runing it
k= minutes(10);
MF= %unaveraged velocity matrix of size 18X24683
Data1.Time = % date time values of size 1X24683
MAMF=movmean(MF,k,2,'SamplPoints',Data1.Time)
Window length must be a finite positive scalar or 2-element vector
of finite nonnegative scalars.
Error in datetime/movmean (line 105)
y = builtin('_movmeandt', args{:});

The error message could be clearer about the problem you're having, but you're getting the message because you've misspelled "SamplePoints". If you fix the spelling, you should get what you need.

I fixed the spelling error now I am getting the error message:
'SamplePoints' value must be a 1-element vector.
Error in datetime/movmean (line 105)
y = builtin('_movmeandt', args{:});

Can you provide a MAT file with your data, and a simple reproduction script?
