Plotting a piecewise returns error
显示 更早的评论
Hello,
Plotting the code below returns the following erro:
syms t
t =[0:0.1:2*pi];
x = 2*sin(t);
%% Plot 1
figure (1)
f_1 = piecewise(t < -1, 1.5*2*sin(t)+1.5, -1 < t < 1, 0,t>1, 1.5*2*sin(t)-1.5);
plot(f_1, t);
Undefined function 'piecewise' for input arguments of type 'double'.
Please help, thank you

t =[0:0.1:2*pi];
delete that line
plot(f_1, t);
instead
fplot(f_1, [0, 2*pi])
