How to find equal values/words between two string vectors?

hi, I would need to find a way to comapre two strings vectors and find the equal value/words. Then I need to know in which position are the equal value. I'll post an exmple:

a=[10, 25, V4E, 64, 33];
b=[64, V4E, T2S, 10, 11];

the output i want to obtain is: c= [1, 3, 4]; which is the position of the equal values in the first vector.

if it's possible it would be awsome to have a second row with the value:

c=[1,   3,   4;
   10, V4E, 64]

thanks in advance!!

a=["10", "25", "V4E", "64", "33"];
b=["64","V4E", "T2S", "10", "11"];
c=find(ismember(a,b))

c = 1×3

1 3 4

d=a(c)

d = 1×3 string array
    "10"    "V4E"    "64"
