Hi there,

I'm trying to create a slightly modified version of linspace.

Linspace returns n numbers between x1 and x2, with constant
spacing.

I want to get n numbers between x1 and x2, but I want the
spacing between numbers to increase/decrease constantly.

Ie, the spacing between output(2:3) should be 0.9 times the
spacing between output(1:2), and the spacing between
output(3:4) should be 0.9 times the spacing between
output(2:3), etc...

I'm pretty sure this can be done in some simple operation
that I just haven't figure out yet...
Any ideas?

Thanks,
Sven.

That's called logspace

x = logspace(log10(x1),log10(x2),n)
