np.argmin The np.argmin () function is used to get the indices of the minimum element from an array (single-dimensional array) or any row or column (multidimensional array) of any given array. The numpy argmin () function takes arr, axis, and out as parameters and returns the array. You have to just change the condition inside the numpy.where () method.
fh = Dataset(fn, mode='r') heights = fh['NASADEM_HGT'][:] lons = fh.variables['lon'][:] lats = fh.variables['lat'][:] min_height = np.min(heights) max_height
By default, the index is into the flattened array, otherwise along the specified axis. If provided, the result will be inserted into this array. It should be of the appropriate shape and dtype. 2021-01-31 · numpy.ndarray.min.

If you want to find the index in Numpy array, then you can use the numpy.where () function. 2020-01-14 · Numpy Partition. It return a partitioned copy of array. Perform an indirect partition along the given axis using the algorithm specified by the kind keyword. It returns an array of indices of the same shape as a that index data along the given axis in partitioned order

It is the same data, just accessed in a different order. The min () and max () functions of numpy.ndarray returns the minimum and maximum values of an ndarray object. The return value of min () and max () functions is based on the axis specified. If no axis is specified the value returned is based on all the elements of the array. numpy.ndarray.min¶ ndarray.min(axis=None, out=None, keepdims=False)¶ Return the minimum along a given axis.

Returns index_array ndarray of ints Let’s get the array of indices of minimum value in 2D numpy array i.e. # Find index of minimum value from 2D numpy array result = numpy.where(arr2D == numpy.amin(arr2D)) print('Tuple of arrays returned : ', result) print('List of coordinates of minimum value in Numpy array : ') # zip the 2 arrays to get the exact coordinates listOfCordinates = list(zip(result[0], result[1])) # travese over the list of cordinates for cord in listOfCordinates: print(cord) Assuming that you want the indices of a list, not a numpy array, try my_list = [5, 3, 2, 1, 1, 1, 6, 1] np.where (my_list == min (my_list)) The index is because numpy returns a tuple of your answer and nothing (answer as a numpy array). Don't ask me why. np.argmin The np.argmin () function is used to get the indices of the minimum element from an array (single-dimensional array) or any row or column (multidimensional array) of any given array.
