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');
