math.radians(x) - convert angle x from degrees to radians Hyperbolic functions Hyperbolic functions are analogs of trigonometric functions that are based on hyperbolas instead of circles. math.acosh(x) - return the inverse hyperbolic cosine of x ...
You can explicitly convert or cast an array from one dtype to another using ndarray’s astype method: In [37]: arr = np.array([1, 2, 3, 4, 5]) In [38]: arr.dtype Out[38]: dtype('int64') In [39]: float_arr = arr.astype(np.float64) In [40]: float_arr.dtype Out[40]...
You want to convert this 3D array into a 2D image with the same height as the original image and three times the width so that you’re displaying the image’s red, green, and blue components side by side. Now see what happens when you reshape the 3D array. You can extract the height...

官网来源:Universal functions (ufunc) — NumPy v1.21 Manual 数学运算(Math operations) 三角函数(Trigonometric functions) All trigonometric functions use radians when an angle is called for. The ratio of degrees to radians is 180∘/π. 逻辑函数(Comparison functions) ...
This takes the sin and cos algorithms from Optimized Routines under MIT license, and converts them to Numpy intrinsics. The routines are within the ULP boundaries of other vectorised math routines ...
