[求助]学过自动控制的请进，想做一个关于控制的gui
<P>请教各位：用gui画图怎么不能用控制里的一些画图的命令啊？我试过了画一些数学函数的图像可以，比如用plot,stem等，但是画step,nyquist都不行，有没有人能帮忙解答？<BR>.m文件如下：<BR>function varargout = my02(varargin)<BR>% MY02 M-file for my02.fig<BR>% MY02, by itself, creates a new MY02 or raises the existing<BR>% singleton*.<BR>%<BR>% H = MY02 returns the handle to a new MY02 or the handle to<BR>% the existing singleton*.<BR>%<BR>% MY02('CALLBACK',hObject,eventData,handles,...) calls the local<BR>% function named CALLBACK in MY02.M with the given input arguments.<BR>%<BR>% MY02('Property','Value',...) creates a new MY02 or raises the<BR>% existing singleton*. Starting from the left, property value pairs are<BR>% applied to the GUI before my02_OpeningFunction gets called.

想请教哈你
我们老师让做，两个文本框，一个坐标。一个文本框可以显示主程序，另一个可以改变其中的参数。例如比例环节中的R2/R1.但是修改参数后不管用.想请问你,怎么弄.
