intprog函数用不了 matlab

因为这个函数不存在，需要自己创建。相关信息如下:

INTLINPROG has stopped because it encountered an internal error. We are sorry for the inconvenience

Please contact technical support for assistance with your problem， quoting the code "-96@30".

出错 example_intlinprog (line 7)

[x，fval]=intlinprog(f，ic，A，b，[]，[]，lb，ub)
