Read and taking selected lat-longs from few .loc files and plot in geoshow

2 views (last 30 days)
I have 92 .loc files in the current folder. The volume of all the files is large. I need to read all the files one by one and select column 2 and 3 (lats and lons) in 30N to 90N latitudinal range. And place them in one .mat file. Therefore with that .mat file I can plot a geoshow map. How to do that?

clear all
myFolder = 'U:\W\';
filePattern = fullfile(myFolder, '*.loc');
Files = dir(filePattern);
for k =1:length(Files)
% k=1
baseFileName = Files(k).name;
fullFileName = fullfile(myFolder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
fid = fopen(fullFileName,'rt');
a = textscan(fid, '%s %s %f %f %f %f %f', ...
'Delimiter',',', 'CollectOutput',1);
M(:) = [a{2}];
M1=M(:,1:2);
lat_idx=find(M1(:,1)>=30 & M1(:,1)<=90);
WSC=M1(lat_idx,:);
end
I have done that much. I think it reads all the files, but giving the output for one file only. It should be somethink like : It will read first file, keep the first and second column and put the other file's first and second column in the same .mat file.
