can we store character in a matlab matrix

for eg:

[a1, a2, a3]:=[1,0,0];
[b1, b2, b3]:=[1,6,0];
[c1, c2, c3]:=[6,0,0];
r1 := [a1, a2, a3];
r2:=[b1, b2, b3];
r3:=[c1, c2, c3];

m = [r1; r2; r3];

whether this is correct code, if not then kindly help me

This is not correct code by a mile. As you've not explained what you're trying to do, as the title of your question does not appear to relate to the very incorrect code you've posted and as it's far from obvious what you're trying to do with that code it's not really possible to go any further.

I would recommend that you learn the basics of matlab. At the very least, follow the getting started tutorial.
