Hello,
I have several text files with the following format: "mmAAnn.txt". I read all the file names in Matlab without a problem. Now, I want to read each text file separately based on the value of "nn" within that filename's string. For instance, I want to decide to read and write in a variable only those filenames with nn=03. How do I do that?
Thank you,
Yiannis

nWant=3;
wildCardName=sprintf('*%02d*.txt',nWant);
d=dir(wildCardName);
Unfortunately, the MATLAB implementation of dir() only recognizes the asterisk as the wildcard symbol; if need more finesse than it either use regular expressions over the collection of names returned with more general form as above or I often will use the OS more powerful facility instead.
