NumPy 不仅支持复数的计算,还有专门处理复数相关的函数,比如复数的绝对值和相位角等。可以使用numpy.abs()和numpy.angle()进行相关计算。例如: # 计算复数的绝对值和相位角abs_value=np.abs(root)angle_value=np.angle(root)print(f"The absolute value of{root}is:{abs_value}")print(f"The angle (in rad...

相位谱可以通过 np.angle(A) 得到。逆DFT 被定义为[a_m = \frac{1}{n}\sum_{k=0}^{n-1}A_k\exp\left{2\pi i{mk\over n}\right} \qquad m = 0,\ldots,n-1.]它与正向变换的差别在于指数参数的符号以及默认的归一化因子 (1/n)。

All trigonometric functions use radians when an angle is called for. The ratio of degrees to radians is 180^{\circ}/\pi. sin(x[, out]) Trigonometric sine, element-wise. cos(x[, out]) Cosine elementwise. tan(x[, out]) Compute tangent element-wise. arcsin(x[, out]) Inverse sine,...
