recursionlimit
get or set the current or maximal allowed depth of nested calls
Syntax
currentMaxDepth = recursionlimit() formerMaxDepth = recursionlimit(newMaxDepth) currentDepth = recursionlimit("current")
Arguments
- currentMaxDepth
Maximal number of nested calls (= depth) currently set.
- newMaxDepth
New maximal number of nested calls to set.
- formerMaxDepth
Former value set, before it was changed
- "current"
input keyword retrieving the current calling depth (before reaching the max one).
- currentDepth
Current calling depth.
Description
Use this function to change the maximal number of nested calls allowed in Scilab. Each script.sce, public or internal (like overloads) functions in Scilab language, or built-in functions compiled from an external language is a level. Default value is set to 1000 levels.
newMaxDepth can be set in Scilab preferences. |
Examples
recursionlimit(20); function testRecursion() printf("recursion: %d\n", recursionlimit("current") - 1); testRecursion; endfunction testRecursion;
//show that cos and %rec_cos increment the current recursion level. recursionlimit(40); function %rec_cos(val) printf("recursion: %d\n", recursionlimit("current") - 1); val.count = val.count + 1; //disp(val.count); cos(val); endfunction a = tlist(["rec", "count"], 0); cos(a)
recursionlimit(10); function [out]=recfib(in) printf("recursion: %d\n", recursionlimit("current") - 1); if in == 1 then out = 1; elseif in == 2 out = 1; else out = recfib(in-1) + recfib(in-2); end endfunction recfib(10); //OK recfib(11); //KO
