MATLAB: Bar graph for two different arrays

Question

I've two different arrays

a = [2 4 6 8 10]
b = [1 3 5 7 9]

now I want to plot these two array on a single bar graph where x axis values ranges from 1 to 4(1 2 3 4) and y axis contain two different bar graph side by side in different colour, it means at x axis value 1 I need two bar of values 2 & 1 similarly on at x axis value 2 I need two bar of values 4 & 3, similarly at x axis value 3 I need two bar of values 8 & 7, similarly at x axis value 4 I need two bar of values 10 & 9.

Answer 1

Didn't read

doc bar

did you? It'll take 1:5 on the x-axis but

bar([a;b].')
