Hullo Sympy Group,
How can I get Sympy to recognize 2+ inequalities in the same expression?
In mathematical optimization it is common to see (and often very
convenient to use) constraint expressions like these:
*3*x <= 2*y +10 <= 3*z*
*10*x >= 15*y >= 20*z >= t*
Which are actually 2 and 3 ine
Hi.
There's an issue for this too:
http://code.google.com/p/sympy/issues/detail?id=2960
Python evaluates "a < b < c" as "(a < b) and (b < c)". Since it's
impossible to override the "and" operator, this always returns the
first one if it evaluate to True or the second one if it evaluate to
True (
Hmm, so I have some example code that I just threw together that implements
a multiple inequality. It isn't pretty in that I spent 5 minutes working
it, and it uses a global, etc., but it's a proof of concept:
-
*In [1]: a, b, c, d = test('A'), test('B'), test('C'), test('D')*
*
*
*In [2]:
Hello,
I am interested by your code.
