Hello,
I am trying to generate code from my simulink file but I get an error just after starting build procedure (at 0.507sec) : "RTWCGEmlParse Error : Compilation errors when generating code.
Component : Simulink | Category : Model error"
After that, all the blocks become yellow and red. I guess that RTW stands for Real-Time Workshop, the previous name of Simulink Coder and that CG stands for Code Generator but I have no idea what this error means and there is no further explanation. My simulink file contains Simulink blocks and a Stateflow chart.
Could you help me please?
I am using Matlab r2014a.
Thank you

Yes, by deleting each block one by one in order to find the guilty one, I've found that the Gain block doesn't like matrix sum and product as values :
I had 3 gain blocks with a gain value of A+B*K (where A, B and K are 3 matrix). So I created a new matrix in the workspace : Anew=A+B*K and replaced the values of the gain blocks by Anew and it worked ! No more errors :)
Hope it will help ;)

My issue seemed to be with the use of nested library blocks. I ended up replacing the inner library block with its implementation. So I still have the same functionality but the interface and model looks a bit different.
