As far as I understood y = logspace(a,b,n) works for logarithms of base 10. For example we can have:

format longG
y = logspace(-2,3,6)
y = 1x6
1.0e+00 *

                      0.01                       0.1                         1                        10                       100                      1000

Is there a similar function or a simple way to perform the same calculation, but with a custom base B (for example a base B=3.5)?

I mean something like this:

a = -2;
b = 3;
n = 6;
B = 3.5;
y = ...?

maybe I found it, but I am not sure:

a = -2;
b = 3;
n = 6;
B = 3.5;
y = B .^ linspace(a, b, n)
y = 1x6
