I have given filename :-'marstest.raw' n=1 m=8
I am getting error as using too many o/p arguments..

Format the rest of the code for legibility and provide the actual line and error message as seen on the screen to pinpoint where precisely, but it appears the problem is/would be related to
_function[]=dct1(filename,n,m)_
Your function has no return variable(s) defined so if you tried to call it while assigning it to a variable name that's what you'd get. That is, if
noout.m contains
function []=nooout(x)
disp(x)
>> noout
Error using noout (line 2)
Not enough input arguments.
>> noout(1)
1
>> z=noout(1)
Error using noout
Too many output arguments.

Matlab is not C; the value of a function is not returned as the function name but only by assigning return values to the dummy arguments listed in the output list.
