Function arr2_conversion

src/memory/utils/mod.rs:659–671

Convert a 2D array between numeric types. Type-safe conversion between different numeric types for 2D arrays, commonly used when interfacing between different libraries or precision requirements. ## Parameters `array2` - Source 2D array to convert ## Type Parameters `M` - Source numeric type `T` - Target numeric type ## Returns New 2D array with same dimensions but converted element type ## U

(array2: Array2<M>)
