Has anybody seen this error before? I was using the MATLAB function "sim" to run the simulink model and got this error. Now when I try to run the simulink model independently, I get this error (whereas before trying to run it via MATLAB, it ran fine).

Any suggestions?

I ran into this error as well (I'm running 2012b 64 bit).

It went away when I restarted Matlab. That's the only solution I've been able to find.

yes, that "solved" it for me too. I was hoping someone could explain why this is happening though.

Yep - same experience here on 2013a 64bit. I was running the simulink model via function sim fine. Then it started giving this error. Re-starting 'fixed' it.

This bug appears also in R2014a, but it is known to Mathworks. It happens because of a hidden breakpoint in an Embedded Matlab function block in Simulink. More details here:

breakpoint error when running a model with an Embedded MATLAB Function block

Probably the easiest thing to do is just restart Matlab, since it clears all the breakpoints.

Same problem but I have no Embedded MATLAB Function block. Just a simple Script -> Function -> sim(modelname) The moment I put breakpoint @ the function bam!

I do not have or use stateflow and there's no b: drive on my machine, so I am puzzled as for where this error is pointing.
