# Storing the inputs of a function on a structure (or cell or array)

given a function such as:
function [z,w] = tempFun(x,y)
z = x+1;
w = y+1;
end
is it possible to store a given pair x,y as a structure (struct('x',1,'y',2), say, or as a cell or anything else...) and then unpack it and apply the function to the output?
(In python this could be done as: temFun( **{'x':1, 'y':2})

d=struct('x',1,'y',2);
[z,w] = tempFun(d)
function [z,w] = tempFun(s)
z = s.x+1;
w = s.y+1;
end

That's exactly it, thanks a lot!

(the only slight upper hand the python code above has over this is that it will map the variables to their righ places, ie. you won't need to store then in the right order:
tempFun( **{'x':1,'y':10}) == tempFun(**('y':10,'x':1})

Well, I'm a beginner in python (didn't get to this point still) , but this topic would be interesting to be debate about. But then do not underestimate the power of MATLAB ;-)
