Moving Average Filter not working

Hey!

So i have this moving average filter that works completely when I'm inserting it directly as code but somehow will return a unfiltered signal when made into a function and calling up into code.

The function

function vectordata = filter_outlier_dwars(vectordata);

M_dwarsversnelling = 100;

for n = 1:M_dwarsversnelling-1
    outlierloos_dwars(n) = vectordata(n);
end

for n = M_dwarsversnelling:length(vectordata)
    TemporaryVariable = 0;
    for m = 1:M_dwarsversnelling
        TemporaryVariable = TemporaryVariable + vectordata(n-m+1);
    end
    
    outlierloos_dwars(n) = TemporaryVariable/M_dwarsversnelling;
    
end

The call up

outlierloos_dwars = filter_outlier_dwars(offsetloos_dwarsversnelling);

Thanks in advance!

Replace the output variable in the first line:

function vectordata = filter_outlier_dwars(vectordata)
% ==>
function outlierloos_dwars = filter_outlier_dwars(vectordata)

With your code you apply the filter but reply the input data.

BY the way, movavg() and filter() are much faster ways.
