logspace with a different base

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

0.0816 0.2857 1.0000 3.5000 12.2500 42.8750

Looks good to me.

Thanks a lot! This is reassuring :-)

Yes. That will generate the desired spacing, for your chosen base.

Many thanks!! Great! :-)

As an aside, LOGSPACE does exactly that inside, just with B=10.

Ah, good to know! Thanks a lot @Stephen23 :-)
