Using function rand, should a matrix of random integers in the interval [55..100] be generated thus:
M = ceil((rand(5,5)+(11/9))*45);?

That looks right if you have to use rand(), for example if this is a school assignment.
Easier would be
M = randi([55 100],5,5);

m=rand([1 20],5,5)

No, that will not work. The randi function accepts as its first input a range to control how large or small the generated random integer values can be. The rand function does not.
m = rand([1 20], 5, 5);
See the examples in the documentation for rand if you want to generate random values (not necessarily integer values) between 1 and 20.
