Can we generate macro function in code, using simulink model and RTW EC auto coder ?

We are currently having lot of for loops , and they are just to fetch the data from a constant array in to a local data array We need to optimze that .

Is there any way in Matlab modelling ,

Can we generate a Macro code , instead of regular C code ,using the library block sets in simulink and RTW-EC Auto code generator ?

that will increase the memory consumption , but my execution can be improved !!

The closest thing that I can think of is to increase the Loop unrolling threshold on the Configuration Parameter window's Optimization Pane, so the indexing code is inlined, instead of using for-loops. I'm not sure if this is what you intend when you say "macro code".

Thanks for the answer .

1) using "Optimization Pane" will be helpful if i had an fixed size array But we are rolling this for loop over the size of array ( which can vary )

hence my code cannot have to be a fixed inline assignment .

2)Yes when I say "Macro code" its something like " #define " in C coding

At the time of compilation( hex file generation - that we put in our controller) these particular part of codes are optimized( Inlined ) by compiler

--> This will be helpful in the case of varying size of array .. that inlining which we are think of achieveing in matlab code gen , will be take care during the compilation process .

Let me know your thoughts
