RTW/XPC target error, I cannot generate code

Hello

I am trying to generate code using RTW/Xpctarget. I get the following error:

CGIR assertion in .\dom_core\lowering\DynamicMatrixTypeLowering.cpp(3110): '!typeIsDynamicMatrixReference(curr_node->type()) && !typeIsDynamicMatrixCompositeReference(curr_node->type())'

on matlab command window and the following error

Unexpected or internal error encountered in "in CGIR: .\dom_core\lowering\DynamicMatrixTypeLowering.cpp line 3110: !typeIsDynamicMatrixReference(curr_node->type()) && !typeIsDynamicMatrixCompositeReference(curr_node->type())
". Please report this to The MathWorks if you can cause it to recur.

This looks like it could be a bug. Please report it to MathWorks Tech Support and see if they can provide a resolution.

Can you give some more information about the model? I've seen this happen when Embedded MATLAB code is involved.

Hi Rajeev, I really don't know the exact cause of the problem to explain how it can be solved, but I have a method to solve it.

I spent more than 8 hours trying to solve this problem and have not found anything in Internet about it. In my case I had several layers of m-files with the %#eml pragma, proper preallocation and running perfectly in a newer matlab version (2011b). Then I tryed to use the model in another computer connected to the hardware (using matlab 2010b) and I got the error.

I just did not call several m-files inside a single EMF anymore, but use other EMF working like "wrappers", just to call the m-files. I did it to debug each code separatelly and then added all blocks into a single matlab model. It worked. Just try not to change the inputs and output sizes of the lower layers, because you can solve the problem for the lower layers but once you get to the highest one that error message appears again.

So... This was the only thing which worked for me.
