compare cell arrays for equality

Hi, I have two cell arrays. One looks like this: glf=['070617', '091216','280217'] and the other one is grmmf=['070617', 280217', '070617','280217']. I want to start with the first element of glf which is '070617' and compare it with all elements of grmmf so that I know the first index in grmmf when the values are equal. And then continue checking all the rest of glf with each element of grmmf. How do we do this? Also, then I want to pair up the equal values in another matrix for later use. Please help. Thanks.

glf={'070617', '091216','280217'};
grmmf={'070617', '280217', '070617','280217'};
