Multidimensional Arrays in Java Vidhu S. Kapadia The Basic Definitions What is an Array? An array is a fixed size sequent
Each dimension's size is saved along with the array, so Matlab knows which element to return when you index not linearly (e.g. A(3,5) for a 5x5 matrix, Matlab knows it should return element A(23) which is 3+(5-1)*5). So in java if an array has size N1xN2x...xNN, and ...
