multiplication error in DLLs created with SIT

[Philip Holoch]

I have a problem with a multiplication in a DLL created with the Mathwork's Matlab/Simulink and National Instruments SIT. When multiplying two values of different types (fixed point types) I get really strange and unexplainable results. When I run the simulation in Simulink only, I do not get the error. But when running the same program as DLL in Labview I get a result of 146.xxx instead of 235. Feel free to chck out the included files (.mdl, .dll, .vi).

I'm desperately looking for solutions.

Go ahead and hook up your error clusters and attach them to an indicator. This way you can see if there is a labVIEW problem with your code.

I cannot run your code myself because of a lack of software but I opened the VI up and saw it was missing error handling.

Meanwhile I found out, that the problem is in the Mathworks' Realtime Workshop. They're already working on a bug fix.
