Function in for loop

Hi I need to read data from .wfm files. Each file has 25 frames from the oscilloscope and I need the y and t data. The filenames are tdpo001_ch1.wfm ... tdpo150_ch1.wfm and I have no idea how to make the middle of the filename as the variable for a for loop. Thanks for the answer in advance!

Use sprintf:

for fileidx = 1:150
   filename = sprintf('tdpo%03d_ch1.wfm', fileidx)
   %... use filename
end

The '%03d' in format string means replace with the string representation of fileidx as integer, padding with zero to a size of 3 characters.
