I have T2.mat which is a table with 12 columns. I want to replace NaN in columns 5:7 (5 to 7) by exactly the next good value in each column. I don't want to replace NaN in other columns.
I searched a lot and tried hard to do this. I was read the question in the link below:
but I want to do this in just columns 5 to 7 and not for rest of the columns. I attached T2.mat if it's help
Does anyone know how I can do this?
Thank you,
Behzad

It's as simple as:
T2 = fillmissing(T2, 'next', 'DataVariables', {'lat', 'lon', 'station_elevation'})
or
T2 = fillmissing(T2, 'next', 'DataVariables', 5:7)
I recommend the first expression as it is clearer as to which variable is to be filled (and will work even if the order of the columns changes).
