I'm trying to define a set of 'random distribution type' as I can use any of them in the parameter of the a funtion I use.
I tried this for example :
x= struct("poisson", exprnd(Mean, size ), "Gamma", gamma(Mean, size))
now i can write
x.poisson to get the random numbers
but if I want to use another variable i.e:
b=poisson
x.b
the last line makes error and dont give me the value of x.poisson
is there a better idea to map a variable with a set of values?
Thank you!

b = "poisson";
x.(b)
