任意的信号卷积:

function y=juanji(f1,f2)
syms x t;
F1=laplace(f1,x,t);
F2=laplace(f2,x,t);
h3=F1*F2;
h4=simplify(h3);
y=ilaplace(h4,t,x);

function plotbutton1_Callback(hObject, eventdata, handles)

%-------------其他------------%
val=get(handles.listbox1,'value');
str=get(handles.listbox1,'string');
vala=get(handles.a,'string');

c=str2num(vala);
valb=get(handles.b,'string');

d=str2num(valb);
