Python WildFunction Beispiele

Beispiel #1

def test_Function():
    f = Function('f')
    fx = f(x)
    w = WildFunction('w')
    assert str(f) == "f"
    assert str(fx) == "f(x)"
    assert str(w) == "w_"

Beispiel #2

def test_functions_X1():
    from sympy.core.function import WildFunction
    x = Symbol('x')
    g = WildFunction('g')
    p = Wild('p')
    q = Wild('q')

    f = cos(5 * x)
    assert f.match(p * g(q * x)) == {p: 1, g: cos, q: 5}

Beispiel #3

    f = cos(5 * x)
    assert f.match(p * g(q * x)) == {p: 1, g: cos, q: 5}
