Interpolate between log 8 = 0.9030900 and log 12 = 1.0791812.

I just learned using Matlab and suddenly got this question to do in Matlab. Can someone help me? Your help is really needed and very appreciated.

step = 0.1;
log10(8:step:12)

Be aware it's linear interpolation:

p(1) + diff(p)/2 % midpoint

gives the same result as your example above.

Uhm, happens I haven't seen you wanted linear interpolation.
