I'm not sure why this isn't working but I'm just trying to load multiple files from a folder and it's not reading my variables in the matrix as a string. I tried converting to chars but I obviously need more than 1 char based on the example below.
subName = ["10", "12"];
InputFolder = 'F:\Graph Data\';
for i = 1:(size(subName)) %through the size of the number of input files
load([InputFolder,'S',(subName(i)),'_data']);
end
I'd appreciate any help

>> subName = ["10", "12"]; size(subName), 1:size(subName)
ans =
1 2
ans =
1
size() with a single parameter always returns a vector with at least two elements. When you give the colon operator a non-scalar value (such as a vector of length 2), then it ignores everything except the first value... which in this case is 1, the number of rows in subName.
load([InputFolder,'S',(subName(i)),'_data']);
You should probably be using something like
load( fullfile(InputFolder, "S" + subName(i) + "_data.mat") )
and better yet would be to assign the result of load() to a variable, instead of "poofing" variables into existence.
