MATLAB: Import and combine multiple XYZ.txt data files into one X, Y and Z column vectors

Question

Hi

I have a large number of txt files with different names, each one has tab seperated values of X Y and Z data in 3 columns. I have been importing each file seperately but there must be a way to import all the files at once into just 3 column vectors? The files themselves are very large. Is it also possible to write the data into one txt file?

Any help on this would be much appreciated.

Thanks

I don't think you can import all the files at once, but you can do so in a loop and append the data from each file to what has already been imported by concatenating the arrays. See the MATLAB FAQ for more details.

HTH,
