7.3 偏微分方程分类
使用sympy.solvers.pde.classify_pde()可以对偏微分方程进行分类。
例:对偏微分方程进行分类
[]:classify_pde(eq)
[]:('1st_linear_constant_coeff_homogeneous',)
function this way:
from sympy import Function, Derivative
from sympy.abc import x, y # x and y are the independent variables
f = Function("f")(x, y) # f is a function of x and y
#fx will be the partial derivative of f with respect to x
fx = Derivative(f, x)
#fy will be the partial derivative of f with respect to y
fy = Derivative(f, y)
结果表明,该方程为第一类线性常系数齐次偏微分方程
