rp = get(handles.edit3,'String');
     rs = get(handles.edit4,'String');
     wp2 = get(handles.edit5,'String');
     ws2 = get(handles.edit6,'String');
[cs,ds] = afd_butt(wp2,ws2,rp,rs);
这是在gui设计中pushbutton1_Callback中的代码，但一按下键，就会提示错误。。如下，，请问是怎么回事啊？急啊
??? Error using ==> mpower
Matrix must be square.

N = ceil((log10((10^(Rp/10)-1)/(10^(As/10)-1)))/(2*log10(Wp/Ws)));

你从EDIT里得到是字符串，要转换成数值的

麻烦问你一下你的这个问题解决了吗
