infinity12138: 32QAM如何实现呀，按照公式计算的话，k=5，k/2是奇数的哇，L算出来就不是整数了

2401_85889463: 感恩🥹

踏雪泥诶: A=str2num(get(handles.fudu,'string')); % 获取信号的幅度 w=str2num(get(handles.pinlv,'string'));% 获取信号的频率 z=str2num(get(handles.zhankongbi,'string'));% 获取方波的占空比 x1=str2num(get(handles.x1,'string')); % 获取横坐标的起始值 x2=str2num(get(handles.x2,'string')); % 获取横坐标的终止值 y1=str2num(get(handles.y1,'string')); % 获取纵坐标的起始值 y2=str2num(get(handles.y2,'string')); % 获取纵坐标的终止值 t=x1:0.01:x2; % 信号的横坐标范围 y=A*square(w*t,z); % 生成方波信号 plot(handles.axes1,t,y,'LineWidth',2); % 绘制方波信号，蓝色，宽度为2 axis([x1,x2,y1,y2]); % 设置坐标轴范围 guidata(hObject,handles); % 刷新数据 报错了：出错 untitled>fangbo_Callback (line 89) y=A .* square(w .* pi * t, z); % 生成方波信号 出错 gui_mainfcn (line 95) feval(varargin{:}); 出错 untitled (line 42) gui_mainfcn(gui_State, varargin{:}); 出错 matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)untitled('fangbo_Callback',hObject,eventdata,guidata(hObject)) 计算 UIControl Callback

m0_67953442: 你好，请问这个按钮点击变色是怎么设置的

m0_72681858: 跑了一遍代码，发现删去-dt后 ask2=jidai.*zb; % 2ASK的模拟调制 会报错
