inline NDView sub_view(ssize_t first, ssize_t last) const¶

Create a subview of a range of the first dimension. This is useful for splitting a batches of frames in parallel processing.

Parameters:

first – The first index of the subview (inclusive).
last – The last index of the subview (exclusive).

Throws:

std::runtime_error – if the range is invalid.

Returns:

A new NDView that is a subview of the current view.
