How can I call variable with a name from the value in cell array??

I have multiple variables

AFEN = (1:10)';
AFMN= (2:22)';
AFDN= (11:15)';

SeedValue{1} = 'AFEN'

and I how choose random number in AFEN with using SeedValue?

for exmple, to perform the following function,,

% 'SeedValue' refer to 'AFEN', so if SeedValue changes, always 
% refer to the right variables.
randi(max('SeedValue'))     

Thanks in advance.

A variant without eval()

%%
sv.AFEN = (1:10)';
sv.AFMN = (2:22)';
sv.AFDN = (11:15)';
SeedValue = 'AFEN';
%%
rn = randi( max( sv.(SeedValue) ) );

btw: I find the name, SeedValue, misleading
