How do I combine strings using strjoin without spaces being introduced?

Hi,

I am currently trying to run a code that goes through several folders of data. I am having a problem with the function strjoin.

I create a string array named conds, and I want to combine it with another string to get a directory. How can I get rid of this space? I do not want to use strrep to remove the spaces, because later on in my code I have a lot of spaces that I don't want deleted.

conditions = ["C1","C2","G1","G2","I-1","I-2","II-1","II-2","III-1","III-2","N1","N2","P1","P2"];
area = '02_Mapping_Small_Area';

for k = 1:length(conditions)
     device = conditions(k);
Home = strjoin(['C:\Users\Me\Desktop\03_Figures\',device]) %Save location
Start=['C:\Users\me\Desktop\',area] %Data retrieval location
% Home = strrep(Home,' ','');
end

>>> Home = "C:\Users\me\Desktop\03_Figures\ C1"

>>> Start = 'C:\Users\me\Desktop\02_Mapping_Small_Area'

The space before C1 that occurs in Home is what I want to get rid of. I guess it has something to do with single and double quotations.

Thanks!

By using the second input argument of strjoin, you can control a delimiter. So the following code can concatenate strings without space.

conditions = ["C1","C2","G1","G2","I-1","I-2","II-1","II-2","III-1","III-2","N1","N2","P1","P2"];
area = "02_Mapping_Small_Area";

for k = 1:length(conditions)
  device = conditions(k);
  Home = strjoin(["C:\Users\Me\Desktop\03_Figures\",device],'');
  Start= strjoin(["C:\Users\me\Desktop\",area],'');
  % Do something
end

But, for your purpose, I believe it would be better to use fullfile and/or dir functions to create folder path, rather than concatenating a strings.

Thanks so much!

Yes, fullfile or dir might be better. Thanks for your input!
