Create simulink block using existing matlab files

[Biruntha]

Hi,

I developed a system for signal processing in matlab.It contains lot of m-files. Now i want to create simulink block using that matlab files. and get the output value(string) in simulink enviorment. how can i do this ?

You could start by checking this:

• Interpreted MATLAB Function

I defined these denoise,lfcc,vqext function in separate matlab file. should i need to create separate interpreted MATLAB Function for each function?

Fm = 100;%length of Frames excursion
 framelnc = 100;%length of Frames excursion
 Fn = 256;%length of Frames sampling frequency 12.500kHz, frame length 020.5ms
 fs = 8000;

 x = wavread('test\test1.wav');

%% Preprocessing: Noise Removal
 IS= 0.25; % initial silence (noise only)
 output=denoise(x,fs,IS);

 y = output;

 %% Extraction of LFCC Features
 feat = lfcc(y,fs);


 %% Extract VQ CODE
 k=16; % number of centroids required
 code1 = vqext(feat, k);

 test = mean2(code1);

 %% Emotions Recognition

 load ('train.mat')

 Class = knnclassify(test , feature, type);

 y=Class

it gives "Not enough input arguments." , "Error evaluating MATLAB function in 'testmodel/Interpreted MATLAB Function'" how can i solve this?
