how to process this in matlab?

i have 500 files in ascii format and each ascii file has different names with (20000*50).i need to find mean,min,max,std for each column(1 to 50) and save them with file name as first followed by values,

ex:

   DATA_201403051101 2.50 1.00 14.00 4.95.....(1*201)

this to be done for 500 files..so my output will in one excel file

Look up input functions: importdata(), dlmread(), csvread(), textscan(), fgetl(). Which you might use depends on what form your input files are in.

Then look up min(), max(), mean(), std() in the help.
