Question

这个Scilab函数应该计算n的阶乘。但它给出了下面所述的错误：

function fac(n)
   if (n<=0) then n = 1
   else 
       n =  n* fac(n-1)     
   end
endfunction

错误在此处说明：

-->fac(23)

 !--error 44 
Wrong argument #2.

Answer 1

你在n =之后的第一行忘记了返回值function，否则它将永远不会返回任何内容

function n = fac(n)

   if (n<=0) then n = 1
   else 
       n =  n* fac(n-1)
   end

endfunction
