xmin = x.min() x = (x - xmin)/(xmax - xmin) print("After normalization array x = \n", x) The output will be as follows: Array Indexing Indexing means refer to an element of the array. In the following examples, we used indexing in single dimensional and 2-dimensional arrays a...
Assuming you have an array of arrays you want to pick the minimum of you could get the minimum as sorted(a.tolist())[0] As someone pointed out you could also do min(a.tolist()) which uses the same type of comparisons as sort, and would be faster for large arrays...

boolean mask. Peaks are the local maxima in a region of `2 * min_distance + 1` (i.e. peaks are separated by at least `min_distance`). If both `threshold_abs` and `threshold_rel` are provided, the maximum of the two is chosen as the minimum intensity threshold of peaks.", 参数...

The numpy namespace is large and contains a number of functions whose names conflict with built-in Python functions (like min and max). An ndarray is a generic multidimensional container for homogeneous data; that is, all of the elements must be the same type. Every array has a shape, a...
