Hey,

I wanted to create two functions:

function model = CreateModel()
p1 = 1;
p1 = p1*30;
p2 = 50;
P = [p1 p2];
model.P = P;
end

and the second one:

function sol = CreateRandModel(model)
P = model.P;
HI = P(2);
sol.HI = HI;
end

They are in the separated mfiles with the names: CreateModel.m and CreateRandModel.m.

I have the problem that in function CreateRandModel I get a following error :

'Not enough input arguments.

Error in CreateRandModel (line 2)

P = model2.P;'

It looks like the second function doesn't see the first one. Could you help me to solve it?

Works fine

p=CreateModel;
s=CreateRandModel(p);
