运行这个函数会报错:TypeError: not enough arguments for format string,原因是'Submit': '%sjdf'里面的%在后面的括号中没有定义,所以就会报错not enough argument(没有足够的参数),所以在遇到这种字符串中携带%的情况下,应该在%前面再加一个%号,这样的话Python解释器就会知道这里的情况,例如 1 2 3 4 a = "...

f = @ (x)-prod(x);最后一行的【@fun】改成【f】,第1行可以保留也可以删除。或者用子函数的方式,把后面几行放在最前面,然后加一个函数定义,即成为这样的程序结构:function xxxA=...[x,fval]=...function f=fun(x)f=...其中,第一个函数的名字xxx可以任意取,保存文件时最好和这个...
