If you have the Signal Processing Toolbox look in the help for chirp():
chirp
Swept-frequency cosine
Syntax
y = chirp(t,f0,t1,f1)
y = chirp(t,f0,t1,f1,'method')
y = chirp(t,f0,t1,f1,'method',phi)
y = chirp(t,f0,t1,f1,'quadratic',phi,'shape')

Can you pleaes help me with this code if you have the experience to do it?
This is the Logarithmic Sweep Rate equation that I am trying to implement:
The starting and ending frequencies are f1 and f2 , respectively.
The sweep rate in octaves per time is R
Thank you in advance!

f1 =
f2 =
R =
t = linspace(0, 5*pi, 2000);
frequency = linspace(f1, f2, length(t));
y = sin(2 * pi * frequency .* (-1 + 2.^(R * t)) / (R*log(2)));
