Comment #8 on issue 1637 by [email protected]: solve([Eq(x+a*y,1),
Eq(x+y+z, 1), Eq(z+3*x)], x, y, z, a) troubles
http://code.google.com/p/sympy/issues/detail?id=1637
Now in master:
In [1]: x, y, z, a = symbols('x,y,z,a')
In [2]: solve([Eq(x+a*y,1), Eq(x+y+z, 1), Eq(z+3*x)], x, y, z)
Out[2]:
⎧ 1 - a 3 -(3 - 3⋅a)⎫
⎨x: ───────, y: ───────, z: ──────────⎬
⎩ 1 + 2⋅a 1 + 2⋅a 1 + 2⋅a ⎭
In [3]: solve([Eq(x+a*y,1), Eq(x+y+z, 1), Eq(z+3*x)], x, y, z, a)
(...)
NotImplementedError: only zero-dimensional systems supported (finite number
of solutions)
All problems reported in this issue were fixed. I'm closing this issue
because adding support for positive dimensional systems should be on our
wish list.
