I have a sim command which is calling my simulink model from my MATLAB script. The arguements are all assignin to the base workspace for the simulink model so it should be calling them ok.
However when trying to run the script I get the error:
Error evaluating expression '[list of inputs]' for 'Input' specified in the Configuration Parameters dialog for block diagram 'my model' : The following error occurred converting from double to opaque:
Error using horzcat
Undefined function 'opaque' for input arguements of type 'double'.

Try to Ctrl+D (update) your model or run the simulation of your model by click the "Run" button, Simulink will report the error regarding the particular block and you need to resolve the error first.

Thanks for that. One of my inports is supposed to be pulling in data which is [1*9] array and it is resolving the dimensionality as 1. Is there a way to force it to resolve as 2D as with the constant blocks?
