Samuel,
Thanks for the response. While the example, I showed is linear, the
equations I want to solve are not. I am thinking I need a third
function which returns a vector. Am I on the right track?
.
Then it would have been great to post a non-linear sample with sin(x),
etc ;)
Only one function -- but vectorized -- is required. Here is an example
(non-linear :):
function Z = f(u)
x = u(1)
y = u(2)
Z = [ sin(x)-y+3
cos(y)+x-2
]
endfunction
s = fsolve([0 0]',f)
[ sin(s(1))-s(2)+3 cos(s(2))+s(1)-2] // Check
--> function Z = f(u)
> x = u(1)
> y = u(2)
> Z = [ sin(x)-y+3
> cos(y)+x-2
> ]
> endfunction
--> s = fsolve([0 0]',f)
s =
2.9999999
3.1411201
--> [ sin(s(1))-s(2)+3 cos(s(2))+s(1)-2] // Check
ans =
4.441D-16 -1.332D-15
// Samuel
