29 paź 2009 · There is a browser interface and an API to Python / MATLAB. The API to Python is a single script (apm.py) that is available for download from the apmonitor.com homepage. Once the script is loaded into a Python code, it gives the ability to solve problems of: Nonlinear equations. Differential and algebraic equations.
Here are some examples. >>> simplify(sin(x)**2 + cos(x)**2) 1 >>> simplify((x**3 + x**2 - x - 1)/(x**2 + 2*x + 1)) x - 1 >>> simplify(gamma(x)/gamma(x - 2)) (x - 2)⋅(x - 1) Here, gamma(x) is Γ (x), the gamma function. We see that simplify() is capable of handling a large class of expressions. But simplify() has a pitfall.

SymPy variables can also be substituted into SymPy expressions. In the code section below, the symbol z is substituted for the symbol x (z replaces x).
In[1]: from sympy.core.cache import clear_cache In[2]: horner_poly = lambda n: horner(sum([ x**i for i in range(n) ])) In[3]: clear_cache(); horner_poly(70).subs(x, 1) 70. In[4]: clear_cache(); horner_poly(71).subs(x, 1) RuntimeError: maximum recursion depth exceeded.
>>> sym. simplify ((x + x * y) / x) y + 1 Simplification is a somewhat vague term, and more precises alternatives to simplify exists: powsimp (simplification of exponents), trigsimp (for trigonometric expressions) , logcombine , radsimp , together.
Python samodzielnie wykonuje wspólne operatory matematyczne, w tym dzielenie liczb całkowitych i liczb zmiennoprzecinkowych, mnożenie, potęgowanie, dodawanie i odejmowanie.
