recursionlimit

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
