Is there any counterpart of MATLAB function numel in java? -

i'm trying use numel (function available in matlab) in java. implementations of function available in java?

i not sure if how want numel work here have few versions:

version1 - arrays irregular size {{1},{2,3}}

this method iterate on elements of array counting them.

public static int numel(object array) {     if (array == null)         return 1;// count nulls elements since new string[10]                     // initialized nulls      int total = 1;     if (array.getclass().isarray()) {         total = 0;         int length = java.lang.reflect.array.getlength(array);         (int index = 0; index < length; index++) {             total += numel(java.lang.reflect.array.get(array, index));         }     }     return total; } 

version2 - arrays regular size new string[2][3][4]

this method use size of first rows of different levels in array size assuming rows @ same level have same size

public static int regularnumel(object array) {     if (array == null)         return 1;     int total = 1;     if (array.getclass().isarray()) {         int length = java.lang.reflect.array.getlength(array);         if (length > 0) {             object row = java.lang.reflect.array.get(array, 0);             if (row == null || !row.getclass().isarray())                 return length;             else //now know row array                 return length * regularnumel(row);         } else             return 0;     }     return total; }
