i have values in command window
t=0:0.1:10;y1=sin(4*t);
y=reshape(bsxfun(@times,repmat(y1,3,1)',[1 3 5]),1,[]);
close,
plot(y) will give the sine wave,but i need this sive wave to be plotted in simulink,and i need to see the graph in scope
please help
if not is it possible to embedded these vales in simulink to get graph in scope

ty=[t' y']
In your Simulink model use From Workspace block from Simulink/Sources and set data to ty

You've used repmat to y then you must change t. try this
t=0:0.1:10;y1=sin(4*t);
y=reshape(bsxfun(@times,repmat(y1,3,1)',[1 3 5]),1,[]);
t=0:0.1:(length(y)-1)*0.1
ty=[t' y']

Thanks a lot Azzi,i got it ,please can you tell is it possible to implement this in simulink by using anyblock,(without using from workspace block).i should not use m file,need to simulate directly in simulink

Use three sine wave block with diffrent amplitudes, pass them through a multiport switch

Azzi i used from workspace block ,but i am not getting increasing sine wave,is the axis worng,if so can you please tell how to change x and y axis in scope
please see this

Because your stop time is 10 s, make it 30 s
