WebThese different kinds of views are described below. Slice views ¶ This is probably the most common source of view creations in !NumPy. The rule of thumb for creating a slice view is that the viewed elements can be addressed with offsets, strides, and counts in the original array. For example: In [ ]: WebMore generally, NumPy uses the notion of strides to convert between a multidimensional index and the memory location of the underlying (1D) sequence of elements. The …
