Try this:
A=1;
B=2;
C=3;
D=4;
varcell = {'A','B','C','D'};
varvctr = [A B C D];
[minvar,idx] = min(varvctr);
msg = sprintf('%s = %d',varcell{idx},varvctr(idx));
msgbox(msg, 'Minimum: ')

i try another method to show the min ans,by table
A=40;
B=6;
C=10;
D=21;
E=17;
F=22;
Name = {'A';'B';'C';'D';'E';'F'};
Value = [A;B;C;D;E;F];
T = table(Name,Value)
rows = min(Value);
vars = {'Name'};
Final = T(rows,vars)
why the final table will not show the name of minimum value, it show the F or 'Row index exceeds table dimensions'.

Notice that Star Strider used
[minvar,idx] = min(varvctr);
and then used the idx value.
You have used
rows = min(Value);
which returns the minimum value but not its position.

Name

if i change
rows = min(Value);
