Good Day, thank you for reading me, i am using matlab R2019 and i have this problem.
I need to eliminate from the vector of wind Velocity values less than 1 and replace with nan in all the row, so the vector of wind direction is also NaN, and everything is ok, but in the final start to replace all with NaN
Can you please tell me, what i am doing wrong
i attach the code and the file.
Thank you very much for your valious time, i know the program is very simple but before it was working
opts = detectImportOptions('tempdat.xlsx','DataRange','A5','VariableNamesRange','A2');
TT = readtimetable('tempdat.xlsx',opts);
TT = retime(TT,'regular','fillwithmissing','TimeStep',minutes(10));Matrix = TT{:,:}; %convert values to matrix
V = Matrix(:,2:3);
VelVien = V(:,1);
ind = (abs(VelVien)<=1);
VelVien(ind)=NaN;
V(ind,:)=NaN;
writetimetable(TT, 'somefile.xlsx');
Best

Could you please show me the error message you get? Your code seems to work in r2020a.

i don't have any error, the thing is in is suppose to replace all the values less or equal to 0 with nan, for the wind velocity, but in the end this is not occur, because in this line i have this:
but the program do this:
(the code is not supposed to remove those values)

What you want the result to be is not obvious.
Try this:
TT(ind,:)={NaN};
.
