diophant - diophantine (Bezout) equation

### Calling Sequence

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

### Parameters

- `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

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)
