I have a question about a code. I have an xlsx file that icludes three columns. The 3rd column has numbers and some NAN values. I use rmmissing command in order to igner them But I see that the other two columns are not be ignored from my code too. I would like to ignore the lines in which the 3rd column includes NaN values
How could I make it?
My code is
filename1= 'TEST.xlsx' %arxeio me makroseismika
[d1,tex]= importdata(filename1);

Don't create sequentially-named variables, use the array MATLAB so conveniently provided you...
filename1= 'TEST.xlsx' %arxeio me makroseismika
[data,tex]= importdata(filename1);
ix=ismissing(data(:,7)); % find those want to eliminate
data=data(~ix,:); % keep those that aren't missing
If you do have disparate data types in the file, I strongly suggest to use readtable handles such in one object instead of having to have two.

I'm afraid that without any other data to use, it follows precisely the code variables you have in your code snippet...if you expect exact solutions, must supply enough information that is a possible task...
That's the problem with importdata bringing in two disparate variables -- they're not necessarily the same size as apparently is the case here. Nothing can do about that without the information.
As said, use readtable instead.

A = d1(:,1);
B = d1(:,2);
C = d1(:,7);
mask = ismissing(C);
A(mask) = [];
B(mask) = [];
C(mask) = [];
