Thread Subject: s-function

Dear Sir,
I am new in using a s-function block with level 2 M-file. I wish to use it for execution of one of .m file with the help of simulink model.
The codes of this .m file are as given below. Can you please guide me that what steps are to be taken to use these codes in a simulink model.

x=wavread('ndata1',8000);
[C,L] = wavedec(x,5,'coif4');
[XD,CXD,LXD] = WDEN(C,L,'rigrsure','s','one',5,'coif4');
y = waverec(CXD,LXD,'coif4')

Regards

Hi,
for all these operation we have a ready made blocks in Signal processing blockset....
Please check the blockset section:
Sig : Sorces:wavread block
Sig:Transform: DWT
Hope may be useful....

Dear Sir,
Thanks for your reply . But i want to use wden function for defining the denoising algorithm of my choice. Is there any block available for that? If not whatis the procedure to incorporate this one in simulink model?
