How to remove more than K consecutive NaN values from row matrix
1 view (last 30 days)

I have a row vector like this:
x=[2 5 NaN NaN 8 11 5 9 12 NaN NaN NaN NaN NaN NaN 4 2 NaN NaN 16 NaN NaN NaN 1 NaN 6 NaN NaN NaN NaN NaN NaN]
and let say k=2
So, I want to remove if consecutive NaN is more than 2, so the output for the above row matrix have to be like this:
x_new = [2 5 NaN NaN 8 11 5 9 12 4 2 NaN NaN 16 1 NaN 6]
Thank you for the help in advance

x=[2 5 NaN NaN 8 11 5 9 12 NaN NaN NaN NaN NaN NaN 4 2 NaN NaN 16 NaN NaN NaN 1 NaN 6 NaN NaN NaN NaN NaN NaN] ;
idx = isnan(x) ;
idr = diff(find([1 diff(idx) 1]));
D = mat2cell(x',idr,size(x,1));
% Remove more than two NaN's
for i = 1:length(D)
if any(isnan(D{i})) && length(D{i})>2
D{i} = [] ;
end
end
iwant = cell2mat(D)'
