I have two vectors a and b, where they are as follows:
I want to draw a histogram of them such that a is on x-axis and b is on y-axis as shown in the given attachement.

Thank you very much Jon for your prompt response. I checked that but that has a single vector x. I have two vectors a and b.So If I make my "a" vector as x, then where is the role of vector b? So that can't help me.

I'm not really sure what you are trying to make a histogram of. It looks like you just want to know how many equally spaced values there are between logarithmically spaced intervals. In this case you don't need the b vector, other than to look at its maximum value which would just set the maximum horizontal scale value. To make sure you don't exceed this value you have to choose your increment properly. Maybe you are looking for something like this?
numBins = 20;
maxCount = 100;
% calculate increment so that maxCount will not be exceeded
delta = (1e-15 - 1e-18)/(numBins*maxCount);
% generate your equally space data
% make your histogram
set(gca,'xscale','log') %scale the x-axis logarithmically
