Hi community! I would appreciate your contribution to the following.
I have created the directory I want (the first of which is C:\Users\dparliari\Desktop\OutputEv\Airport\Temperature) using the following lines:
output_path='C:\Users\dparliari\Desktop\OutputEv'
vars={'Temperature'; 'Relative humidity'};
for m=1:size(vars,1)
if(~exist([output_path,'\',namestr,'\',strrep(vars{m},' ','_'),'\'],'dir'))
mkdir([output_path,'\',namestr,'\',strrep(vars{m},' ','_'),'\'],'dir')
end
end
Now I want to create a subfolder based on the year in this way: C:\Users\dparliari\Desktop\OutputEv\Airport\Temperature\2015
I guess it must be something like:
output_path='C:\Users\dparliari\Desktop\OutputEv'
vars={'Temperature'; 'Relative humidity'};
years = {'2015'; '2019'};
for m=1:size(vars,1)
if(~exist([output_path,'\',namestr,'\',strrep(vars{m},' ','_'),'\'],'dir'))
mkdir([output_path,'\',namestr,'\',strrep(vars{m},' ','_'),'\'],'dir')
for k = 1:size(years,1)
if(~exist([I HAVE NO IDEA!!))
mkdir([ALSO NO IDEA!!)
end
end
end
Any ideas please??

Use fullfile, Build full file name from parts that makes the code more robust and readable.

Sorry I didn't get it. Can you please explain a bit further?

As Per isakson said, use fullfile instead of building paths manually. fullfile automatically inserts the correct path separator for whichever OS your code is running on.
I would do it like this
output_path='C:\Users\dparliari\Desktop\OutputEv';
vars={'Temperature'; 'Relative humidity'};
years = {'2015'; '2019'};
[vv, yy] = ndgrid(vars, years); %note that this syntax is not officially supported. If it's a problem use
%[vv, yy] = ndgrid(1:numel(vars), 1:numel(years)); vv = vars(vv); yy = years(yy);
allfolders = fullfile(output_path, 'Airport', vv, yy);
for fidx = 1:numel(allfolders)
if ~exist(allfolders{fidx}, 'dir')
mkdir(allfolders{fidx});
end
end

First, you need to learn to use tables properly.
stations(x, y)
uses () indexing and thus returns a table (the portion of the table referenced by indices x, y.
stations{x, y}
uses {} indexing and thus returns the content of the table.
Another way to get the content is with . indexing:
stations.y(x)
So, instead of:
network = stations (i, 'Network');
% ...
networkstr = char(network.(1));
simply:
networkstr = char(stations{i, 'Network'});
or
networkstr = char(stations.Network(i)); %probably simpler
I'm not convinced the char() conversion is even needed.
So I can understand better what your code is doing, can you attach an example input table?

I am attaching the list of stations and an example of data (excel file).
Plus you are correct, line
networkstr = char(network.(1));
works exactly as
networkstr = char(stations{i, 'Network'});

Try this
%%
output_path = 'd:\m\cssm'; % 'C:\Users\dparliari\Desktop\OutputEv'
vars = {'Temperature', 'Relative_humidity'};
years = {'2015', '2019'};
for vv = vars
for yy = years
ffs = fullfile( output_path, 'Airport', vv{:}, yy{:} );
mkdir( ffs );
end
end

Should be 'Airport' not Airport
