How do i extract values from a name-value pair argument?

Can someone help me on this please. my function is this; fid=fopen('20160613.XVI'); C=textscan(fid,'%s%s','CollectOutput',true,'Delimiter',';'); data=C{1}(71:73,1); [~]=fclose(fid);

It returns the following; {'CouchShiftLat=-0.17' } {'CouchShiftLong=-0.08' } {'CouchShiftHeight=-0.09'} But i needed only the values; -0.17,-0.08 and -0.09.

I am now able to read the values i wanted using the function below:

fid=fopen('20160613.txt');

C=textscan(fid,'%s%s','CollectOutput',true,'Delimiter',';=');

celldata=C{1}(73:75,2);

data=str2double(celldata)

[~]=fclose(fid);

My next task now is to read this from multiple files(1,2...n). Attached here is a sample of my data file.

many thanks

files = dir('*.txt') ;   % Get all text files of the folder 
N = length(files) ;     % Total files 
% loop for each file 
for i = 1:N 
    file = files(i).name ;
    % do what you want 
end

Thanks for your prompt feedback. sorry i am very new to matlab. the 'name' meaning the name of the folder or the files in the folder?

Also, what about the code I generated that reads specific section (data needed) in a single file? No need for it here? Thanks

"the 'name' meaning the name of the folder or the files in the folder?"

dir returns a structure. One of the fields of that structure is called name: it contains the names of the files/folders. Read more here:

Note that it is good habit to avoid length entirely, and only numel and size.

It works perfectly. Thanks a million
