Description

Use this function to change the recursion of Scilab. each built-in, macro or overload is a level. This parameter can be setup in Scilab preferences. Default value is set to 1000.

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
