How can i use If block for a matrix in SIMULINK?

My block-set should use if block and convert any value of the given matrix from current value to 5 if a value greater than 0.

How can i do this operation?

Thx!!

I have just added the model and image.

Ok lets use some vectorised method (logical indexing):

Thank you madhan ravi. Now, i am testing the this operation with using code.

If any value of matrix equals to 2, it should be converted to 15.

I use this code for this, but i got an error. Have you any think to solve this type of problem?

function y = fcn(u)
t=1:5;
if u(t)==2
    u(t)=15
end
y = u;

@Alex: Just use the same logic I showed you, I have some work to do, will return to you after a while [couple of hours] (do some experimentations with the logic) until then ;-).

Ok ravi. Thanks a lot! :)))

[madhan ravi]

function y = fcn(u)

y = u;
y(u==2)=15

Thank you madhan ravi.

Yesterday, after your message, i completed the codes which are similar to yours. Thanks a lot! :)

No mention, glad ;-).
