Conversion of .slx file to .mdl format?

I am right now using MATLAB 2011 ,but i have a simulink file,sampling.slx(link given below)that i am unable to open,can some one please convert that to .mdl format,so i may use it in MATLAB 2011?

Thanks in advance

I don't know if there are specific version dependencies between R2011a and R2011b, so I just did both. I didn't try to run any of them, so no guarantees anything works.

Many thanks for your kind response, When i try use,it is opening in simulink,nice,but when i try to call it through M-file,i get the following error:

Error using sampling_m_file (line 28)

All sample times for 'sampling_R2011a/Spectrum reconstructed signal/Optional Buffering/Buffer' must be

discrete.

No continuous or constant sample times are allowed

Code of m-file is below:

% f - The frequency of analog sinusoid signal

% F - Sampling Rate

% qbits - Number of Quantization bits

% A - Amplitude of sinusoid signal

% L - Number of quantization levels based on qbits

% I - Quantization Interval

% sim_time - Simultaion Time

% span - x-axis range of frequency plot 1 & 3 (spectrum scope 1 & 3)

% span1 - x-axis range of frequency plot 2 (spectrum scope 2)

% NFFT - Number of FFT points

clc;

clear;

close all;

f = input('Enter the frequency of signal = ');

F = input('Enter the sampling frequency = ');

A = input('Enter max amplitude of signal = ');

qbits = input('Enter the number of quantization bits = ');

fc = input('Enter the lowpass filter cutoff frequency = ');

L = 2^qbits;

I = 2*A/(L-1);

% Settings for Spectrum Scope

span = 9*F;

span1 = 9*F;

NFFT = 256;

% To run simulink model

t = 1/f;

sim_time = 10*t;

sim('sampling_R2011a.mdl');

Is this of any help?

I am unfamiliar with the model and simulink barely even runs on this computer.
