| ``mx.nd.argsort`` |
| ================================== |
| |
| Description |
| ---------------------- |
| |
| Returns the indices that would sort an input array along the given axis. |
| |
| This function performs sorting along the given axis and returns an array of indices having same shape |
| as an input array that index data in sorted order. |
| |
| |
| **Example**:: |
| |
| |
| x = [[ 0.3, 0.2, 0.4], |
| [ 0.1, 0.3, 0.2]] |
| |
| // sort along axis -1 |
| argsort(x) = [[ 1., 0., 2.], |
| [ 0., 2., 1.]] |
| |
| // sort along axis 0 |
| argsort(x, axis=0) = [[ 1., 0., 1.] |
| [ 0., 1., 0.]] |
| |
| // flatten and then sort |
| argsort(x, axis=None) = [ 3., 1., 5., 0., 4., 2.] |

| Arguments |
| ------------------ |
| |
| +----------------------------------------+------------------------------------------------------------+ |
| | Argument | Description | |
| +========================================+============================================================+ |
| | ``data`` | NDArray-or-Symbol. | |
| | | | |
| | | The input array | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``axis`` | int or None, optional, default='-1'. | |
| | | | |
| | | Axis along which to sort the input tensor. If not given, | |
| | | the flattened array is used. Default is | |
| | | -1. | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``is.ascend`` | boolean, optional, default=1. | |
| | | | |
| | | Whether to sort in ascending or descending order. | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``dtype`` | {'float16', 'float32', 'float64', 'int32', 'int64', | |
| | | 'uint8'},optional, | |
| | | default='float32'. | |
| | | | |
| | | DType of the output indices. It is only valid when ret_typ | |
| | | is "indices" or "both". An error will be raised if the | |
| | | selected data type cannot precisely represent the | |
| | | indices. | |
| +----------------------------------------+------------------------------------------------------------+ |
| |
| Value |
| ---------- |
| |
| ``out`` The result mx.ndarray |
