Regular expression while import data

I have a nearly 360 folders which individual folder contains 400 .mat files. There are basically two structure in file names. Like

20130103_083800_p001_calc.mat
20130103_083800_p001.mat
20130103_083800_p002_calc.mat
20130103_083800_p001.mat

I have created script to load and do some calculations ( mean ) of every column of data.This script works for all files. Now I only want to load files without "calc" in their file name.

numfiles = 10;
mydata = cell(1, numfiles);

for k = 1:numfiles
  myfilename = sprintf('20130103_083800_p00%d.mat', k);
  mydata{k} = importdata(myfilename);
  fprintf('value of k: %d\n',k);
  if k==1
   a=mean(mydata{1,1}.module02.data,1)
   a=[mydata{1,1}.startTime a];
  end 

    temp1=mean(mydata{1,k}.module02.data,1)
    temp1=[mydata{1,k}.startTime temp1];
    a=[a;temp1];
  end

Can any one suggest me. I will be really great full. I need to process many directories like this.

That script will never try to importdata() from a file with "calc" in its name.

Anyhow, if you have a filename, perhaps found via dir(), then

if regexp(filename, '_calc')
  %then there was a _calc so react appropriately such as with "continue"
end

I have made some changes from above script like below;

    matFiles = dir('*.mat'); 
  numfiles = length(matFiles);
  mydata = cell(1, numfiles);
  temp2=0;

for k = 1:numfiles
  mydata{k} = load(matFiles(k).name); 
  fprintf('value of k: %d\n',k);
  if k==1
   a=mean(mydata{1,1}.module02.data,1)
   a=[mydata{1,1}.startTime a];
  end 

    temp1=mean(mydata{1,k}.module02.data,1);
    temp2=temp2+temp1;
    temp1=[mydata{1,k}.startTime temp1];
    a=[a;temp1];
  end

This works for me to load all mat files and do some calculations.But now need to use regular expression like you said is it possible ?

Guessing a bit at what you want:

matFiles = dir('*.mat'); 
not_calc = cellfun(@isempty, regexp({matFiles.name}, '_calc'));
matFiles - matFiles(not_calc);

and then continue on with numfiles = and so on.
