Hello everyone,
I am trying to gradually plot a graph as if its plotting in real time. I have tried a code but it doesn't seem to work saying Subscript indices must either be real positive integers or logicals.
Here's my code:
clc
a = 0:0.1:10;
x = sin(2*pi*3*a);
for i = 0:1:100
plot(a(i),x(i))
pause(1)
end
can anyone help me with this?

a = 0:0.1:10;
x = sin(2*pi*3*a);
for i = 1:length(a)
plot(a(1:i),x(1:i))
pause(1)
end
However I recommend that you read about animatedline()
