How to create a matrix in matlab using variables?

Question

I have four variables which I created using NetCDF data namely height, lat, long and date. Now I want to create a single matrix with these variables as a column then I supposed to neglect values containing "NAN" data.

I have done this separately, but I want in a single matrix. I have to run this process on multiple files.

for i = 1:length(theFiles)% Loop for each nc-file
    %Select Single cycle
    FileName = theFiles(i).name; 

    FullPathName=fullfile(folder_name, FileName); %reading file one by one
    disp(['File selected:', FullPathName])


    [Height,time,Lat,Long]=read_netcdf(FullPathName);  % Read the selected nc file 
     lattiude=Lat;
     longitude=Long;

     B = [Height,time,Lat,Long];   
    end 

One more thing, total no. of data is 579X1 all variable but as I remove Nan value from Height, its dimension reduces to 45X1 Now what I am trying to do is to reduce all the variables dimensions wrt Height.

I have got my matrix, now wanted to remove all rows containing Nan Value

Answer 1

Not sure if this is what you are asking, but you can increase the size of arrays like this:

for i = 1:n
   B = [B; newValue];
end
