MATLAB: Point out the error

animationvibrating guitar

Matlab script to animate the motion of vibrating guitar

A= 2;
L= 10;
f= 50;
ta= 2;
x=0:0.1:L;
T=5 ;
t=0;
for t < T
    y=(A)*(exp^(-t/ta))*(sin((2*pi*x)/L))*(cos(2*pi*f*t));
    plot(x,y)
    t=t+0.1;
    pause(0.5)
end

Best Answer

"for" must be followed by a variable name and then by an "=" and then an expression. The "for" loop will then be repeated assigning the values of the expression to the variable in turn.

You probably want "while" instead of "for"

You need to change * to .* and change e to exp(), and you need to move the 5 exponent:

t=0:0.01*pi:20*pi; % Create t
[x, y] = bird(t); % Call the function.
function [x,y] = bird(t)
x = sin(t) .* (exp(cos(t)) - 2*cos(4*t)-sin(t/12).^5)
y = cos(t) .* (exp(cos(t)) - 2*cos(4*t)-sin(t/12).^5)
plot(x,y)
end

Ta=250 ;
Tb=500/2.2 ;
t=1:500 ;
g1=0.07 ;
g2=0.004 ;
Wa = 0.06 ;
r = zeros(length(t),1) ;
r(t<=Ta) = 1-exp(1)-g2*t(t<=Ta) ;
r(t>Ta) = 4*exp(1)-g1*(t(t>Ta)-Tb).*(sin(2*pi*Wa*t(t>Ta))+1) ;
plot(t,r)
