# diophant

diophantine (Bezout) equation

### Calling Sequence

`[x,err]=diophant(p1p2,b)`

### Arguments

p1p2

polynomial vector `p1p2 = [p1 p2]`

b

polynomial

x

polynomial vector [x1; x2]

### Description

`diophant` solves the bezout equation:

`p1*x1+p2*x2=b` with `p1p2` a polynomial vector. If the equation is not solvable, `err = ||p1*x1 + p2*x2 - b|| / ||b||`

else `err = 0`.

### Examples

```s = poly(0, 's');
p1 = (s+3)^2;
p2 = (1+s);
x1 = s;
x2 = (2+s);
[x,err] = diophant([p1 p2], p1*x1 + p2*x2);
p1*x1 + p2*x2 - p1*x(1) - p2*x(2)```
