make log spacing, specifying the length of the first interval

Hi

Let say I want to divide one second into 10 points, where the first length is 8 ms. How can I do that?

the logspace function does not give the option of defining the length of the first interval.

The closest I can get is logspace(log10(0.1),log10(1),10), but the first invertal is on only 3 ms.

It is not possible to logspace a finite number of intervals that include time 0.

Perhaps what you would like is:

F = 0.08; L = 1; N = 10;
t = [F F.*(L/F).^(1/(N-1)).^(1:N)];

hi, specify the first length :

 % Logspace
 s=logspace(0,1,10)/10;
 s(1)=0.008; % 8 ms

 % Or linear Space
 s2=linspace(0,1,10);
 s2(1)=0.008; % 8ms
