Excluding files with a certain keyword in them

I am trying to get data from many CSV files, some of which are unneeded. These unneeded files all contain the word Composite (specifically _X0_00XX0_Composite.csv where X is a placeholder for some letter and 0 is a place holder for some number). Is there a way to tell my program to not attempt to read these files? The data is not needed and is not formatted for my program and I run into issues when trying to read the data. I assume it would be some sort of if statement, where it checks the file name for 'composite' and if true, I need it to break and continue scanning the other files.

Assuming you have the file name as a variable, I'll use myName:

myName = lower(myName);
idx = strfind(str,'composite');
if ~isempty(idx)
  %do nothing
else
  %do something
end

You need to find if 'Composite' is in the file name. strfind() returns the indices where it finds the match as a vector, if it doesn't find anything, it returns the empty vector. If you check whether or not the vector is empty, you can check whether or not 'Composite' is in the file name. I used lower() because strfind() is case sensitive. If case matters, you can just ignore the line

myName = lower(myName);

Cool, thanks. In your example, if the filename did contain composite, how would I go about breaking the current operation and moving onto the next file? Would I replace %do something with break? How would this fit into my above code? Would I need to put the majority of the contents of the 3rd for loop where %do something currently is? I tried that and none of the files got read.
