MATLAB: Code reuse between several Embedded Matlab Function

embedded matlab functionsimulink

Is it possible to share code between several Embedded Matlab Function blocks rather than to duplicate it ? For instance, if I have 2 blocks B1 and B2 which need to use the same function y = f(x) embedded in each block, how to avoid a duplication of the code of the function f() in each block ?

I think you just need to define the function with the %#eml (%#codegen starting in R2011a) directive, and place it somewhere on the MATLAB path. You can then call this function from multiple Embedded MATLAB Function blocks.

MATLAB: Net reusing

Inside your loop, the input to train() is definitely the value of "net" that just calculated in the previous. I am guessing you want to do something like this instead:

net0 = patternnet(10);
% net0 initialization
% ...
for ii=1:10
   net = train(net0,in,tar);
   netSet{ii} = net;
end

This way, you are starting from the initialized value "net0" each time. I don't know enough about neural nets to know if train() has some randomness in it that will make each value of netSet(ii) different.

Also, note that you do not really need the intermediate value "net" inside your loop. You could just do

for ii=1:10
   netSet{ii} = train(net0,in,tar);
end
