What is the memory layout of NumPy arrays?
NumPy arrays can be stored in two main layouts: C-contiguous (row-major) and Fortran-contiguous (column-major).
Can you explain the difference between C-contiguous and Fortran-contiguous?
Sure! C-contiguous means that the last axis is stored contiguously in memory, while Fortran-contiguous means the first axis is stored contiguously.
How does this affect performance?
The memory layout can impact performance, especially in operations that involve looping through the array. C-contiguous arrays are generally faster for row-wise operations.
What about memory usage?
Both layouts use the same amount of memory for the same data, but the layout can affect how efficiently that memory is accessed.
