Example

This example introduces us to the world of MATLAB/octave when dealing with functions (and "handles"):

Our first, very simple, program is just our function, f:

a = b*100;

return %a

end

At this point we could evaluate it at some value by using the feval function:

octave:1> feval('f',2)ans = 200

But what we really want is to pass this to our "bigger" program that will do more operations (like program two here):

low=feval(ff,l);

high=feval(ff,u);

return %return the upper and lower bound [low,high]

end

Which we run using the "handle" mechanism like above (for function f or ANY function):

octave:1> [ll,hh]=sim('f',2,5)ll = 200

hh = 500

octave:2> [ll,hh]=sim(@f,2,5)

ll = 200

hh = 500

octave:3> [ll,hh]=sim('cos',2,5)

ll = -0.41615

hh = 0.28366

octave:1> [ll,hh]=sim('cos',0,pi)

ll = 1

hh = -1
