Thread Subject: filename as function argument

hello all,
i have written a function that will import a .wav file for analysis using MATLAB's wavread funtion. I am trying to have the filename be an input to the function (in addition to the input arguments which so far have posed no problems) instead of hardcoding the filename into the function, but cannot seem to get this to work.

can anyone advise?

thanks much,
steve antonelli

Just pass in a string variable containing the filename.

i cant seem to get it. perhaps it is the syntax?
i have [outs] = func(in1,in2,in3,filename)

but when the function tries to run with the file tuned.wav i get:
??? Undefined function or variable "tuned.wav".

Are you passing the filename in quotes???
filename = 'somefile.wav';
 [outs] = func(in1,in2,in3,filename)
