Question

matlab 函数递归死循环怎么改？

以下是源程序：
function mask = shift2mask(prpoly, shift)

error(nargchk(2,2,nargin,'struct'));

if isscalar(prpoly)
if (prpoly < 3) % => [1 1]
error(message('comm:shift2mask:InvalidPrpolyParameter'));
end
prpoly = de2bi(prpoly, 'left-msb');
end

if ( ~( isvector(prpoly) && ~isempty(prpoly) && ~isscalar(prpoly) ) | ...
any(prpoly~=1 & prpoly~=0) | prpoly(1)==0 | prpoly(end)==0)
error(message('comm:shift2mask:InvalidPrpoly'));
end

if ( ~isscalar(shift) | ~isreal(shift) | floor(shift) ~= shift )
error(message('comm:shift2mask:ShiftNotScalarInt'));
end

ord = length(prpoly)-1;
if ord > 53
error(message('comm:shift2mask:OrderGreaterThan53'));
end

shift = rem(shift, 2^ord - 1);
if (shift < 0)
shift = shift + 2^ord - 1;
end

% Function call函数调用
mask = shift2mask(prpoly, shift);
出现错误：
Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N)
to change the limit. Be aware that exceeding your available stack space can
crash MATLAB and/or your computer.

Error in shift2mask
求大神指导怎么改？尝试过改 set(0,'RecursionLimit',N)中的N为1000甚至1500，都不行。改1500直接关闭了

<p>%可以这样写:</p> <p>function F = nn(n) ??? if n<=1???????????????????? %... ??? %递归调用 ??? end end</p> <p>%Matlab 2009 + Win7 32位 测试通过</p> <p>%运行结果如下:</p> ...

追问

呃，有点看不懂，大神能给详细解释一下么？
