Hi, I want to call data in the matrix by using string which is defined by rand command.

A=[1 2]
B=[2 3]
C=[3 5]
corners = 'ABC'
randompick = corners(randi(numel(corners)))
disp(randompick)
randompick(1) 

Here I cant get any first row numbers of the A, B, and C.

What's wrong in this script?

Thanks.

Desired answer is

Same as what A(1), B(1) or C(1) give after randomly chosing.
