Implementations:
1)Function with stride: https://github.com/NVIDIA/cutlass/blob/main/include/cute/stride.hpp#L102
2)Function without stride: https://github.com/NVIDIA/cutlass/blob/main/include/cute/stride.hpp#L152

function with stride is easy to understand, but without stride, why need to compute like: i = c0 + s0 * (c1 + s1 * (c2 + s2 * ...))

How to use the last function, and also for idx2cor.
