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; }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
