Return evenly spaced numbers over a specified interval. (在start和stop之间返回均匀间隔的数据) Returns num evenly spaced samples, calculated over the interval [start, stop]. (返回的是 [start, stop]之间的均匀分布) The endpoint of the interval can optionally be excluded. Changed in version 1.16.0...
>>> a = np.arange(12)**2 # the first 12 square numbers >>> i = np.array( [ 1,1,3,8,5 ] ) # an array of indices >>> a[i] # the elements of a at the positions i array([ 1, 1, 9, 64, 25]) >>> >>> j = np.array( [ [ 3, 4], [ 9, 7 ] ] ) # a ...
arange()is a function in Python’s NumPy library, which generates arrays with evenly spaced values within a specified range. It is a versatile and efficient tool for creating sequences of numbers, making it fundamental in numerical computing tasks. This function is particularly useful when you ne...
