MATLAB: Load

loadtext file

in matlab I can save and load for example like this
>> mymat=rand(2,3)
mymat =
    0.2785    0.9575    0.1576
    0.5469    0.9649    0.9706
>> save testfile.vg mymat -ascii >> save testfile.vg mymat -ascii >> clear >> load testfile.vg
but in this assignment I was asked to download a file from the internet that was a vector
the assignment said I should load it with this command
TRD = load('TRONDHEIM_MT_Daily.txt');
i saved is as
trondheim_MT_Daily.txt
and it worked to load it
with the way they noted but the filetype is different from other matlab files. I cant find any information about it on internet. Is .txt an own file type and does anyone know where to find information about it if it is?

Hi Tor,
I don't 100% understand the question: .txt is just as .dat or similar an "indicator" that it's a text file (ascii, not yet nothing to do with MATLAB). The load (as you experienced with testfile.vg) is capable of reading "plain" ascii text files. If the text file contains more than just numbers (like header, dates, etc.), then the other functions for reading ascii files come into play (doc iofun gives an overview).
