From workspace block error

I run the following code : wave.time=t; wave.signals.values = val; wave.signals.dimensions=1; where t and val are vectors. I call a simulink model and a from workspace block reads the wave structure. Then i get Undefined function or variable 'wave' error and i don't know what is wrong. Any ideas would be helpful.

Where are you declaring wave structure, on command window OR in script OR in function?
How you are running simulink model, directly from simulink GUI or from m-file?

The wave structure is declared within a function. In the same function i call simulink with the sim command.

Vaiables declared in a fucntion remains within the function scope, while by default simulink resolve the parameters from base workspace. So either declare the variables in the base workspace or change the parameter source for model to current m-function using simset command.
See Run a model in Simulink from MATLAB function where Simulink parameters are defined in this function
