How to extract specific data?

Hello,

a1 = [10 20 30 40 50 60];

b1 = [11 21 31 41 51 61];

c1 = [12 22 32 42 52 62];

1. I want to extract specific data such as

A1 = [10 11 12]

B1 = [20 21 22]

C1 = [30 31 32]

....

F2 = [60 61 62]

and plus,

2. e = [0 3 6];

I want to figure A1,B1,C1,....F1 in one figure,

plot(e,A1,e,B1,.....)

but it has too much groups(A1,B1,C1,...) , so I can't use 'hold on' and plot each group or array each groups.

Could someone know how to plot all groups at one figure?

Thanks for helping me.

Try this:

a1 = [10 20 30 40 50 60];
b1 = [11 21 31 41 51 61];
c1 = [12 22 32 42 52 62];
e = [0 3 6];
abc = cat(1, a1, b1, c1);

figure
plot(e, abc, '-x')
grid

producing:
