mindsponge.common.rots_expand_dims

mindsponge.common.rots_expand_dims(rots, axis)[source]

Adds an additional dimension to rots at the given axis.

Parameters

rots (Tuple) – The rotation matrix is \((xx, xy, xz, yx, yy, yz, zx, zy, zz)\), and xx and xy have the same shape
axis (Int) – Specifies the dimension index at which to expand the shape of v. Only constant value is allowed.

Returns

Tuple, rots. If the value of axis is 0, and the shape of xx is \((..., X_R)\),: where X_R is any number, and the expanded shape is \((1, ..., X_R)\). Return expanded \((xx, xy, xz, yx, yy, yz, zx, zy, zz)\).

Supported Platforms:: Ascend GPU
