Invoke parameters from comsol in matlab

I would like to invoke parameters from comsol in matlab, the code is as follows
model.param.set('N', '5');
num=model.param.N;
Error in num=model.param.N;
And how to invoke the parameter 'N' in matlab? Is there any other way to do this? Any help is appreciated.

In recent versions of Comsol you can do:
[num,unit,expr] = mphevaluate(model, 'N');
which will evaluate the expression for N and returns the numerical value, unit and original definition. In your case it is just a number, but the expressions for parameters can of course be much more complicated than that.
In older versions of Comsol you have to do something like this:
expr = model.param.get('N');
and
value = model.param.evaluate('N')
mphevaluate handles complex parameters automatically. If your parameters are complex you have to use evaluateComplex instead of evaluate in the code above.
