if we take the value of t from 1 to 100 then plot is ok but we take the value of time in reverse then plot is not able
wrong size is showing is there any method to take value in reverse to plot for example
t=100:1
t=zeros(100.1)
y=zeros(100.1)
for i=100:1
y(i)=sin(t(i))
plot(t,y)
end
plot is not showing

i think you don't need a loop here
t=100:-1:1;
y=sin(t);
plot(t,y)

you are req to apply this in this equation
sigma = 10;beta = 8/3;rho = 28;f = @(t,a) [-sigma*a(1) + sigma*a(2); rho*a(1) - a(2) - a(1)*a(3); -beta*a(3) + a(1)*a(2)];[t,a] = ode45(f,[0 100],[1 1 1]); plot3(a(:,1),a(:,2),a(:,3))
set(gca,'XDir','reverse')
