A function that modifies the address stored by a pointer argument can be instrumental in various scenarios, such as reallocating a dynamic array to a larger size: void reallocateArray(int **array, int newSize) {
Many functions in external libraries pass arguments by reference. When you pass by reference, you pass apointerto the value. In the function signature, pointer arguments have names ending inPtrandPtrPtr. Although MATLAB®does not support passing by reference, you can create a MATLAB argument, ...
