| ``mx.nd.Concat`` |
| ================================ |
| |
| Description |
| ---------------------- |
| |
| Joins input arrays along a given axis. |
| |
| |
| .. note:: `Concat` is deprecated. Use `concat` instead. |
| |
| The dimensions of the input arrays should be the same except the axis along |
| which they will be concatenated. |
| The dimension of the output array along the concatenated axis will be equal |
| to the sum of the corresponding dimensions of the input arrays. |
| |
| The storage type of ``concat`` output depends on storage types of inputs |
| |
| - concat(csr, csr, ..., csr, dim=0) = csr |
| - otherwise, ``concat`` generates output with default storage |
| |
| |
| **Example**:: |
| |
| |
| x = [[1,1],[2,2]] |
| y = [[3,3],[4,4],[5,5]] |
| z = [[6,6], [7,7],[8,8]] |
| |
| concat(x,y,z,dim=0) = [[ 1., 1.], |
| [ 2., 2.], |
| [ 3., 3.], |
| [ 4., 4.], |
| [ 5., 5.], |
| [ 6., 6.], |
| [ 7., 7.], |
| [ 8., 8.]] |
| |
| Note that you cannot concat x,y,z along dimension 1 since dimension |
| 0 is not the same for all the input arrays. |
| |
| concat(y,z,dim=1) = [[ 3., 3., 6., 6.], |
| [ 4., 4., 7., 7.], |
| [ 5., 5., 8., 8.]] |
