Repeated sequence of numbers in a vector

Dear MATLAB experts,

I was wondering how can I count the number of times a sepcific sequence of numbers apears in a vector. In adittion, how can I calculate the maximal number of times this sequence apeared in a consecutive order.

For example:

I have a vector M = [1,2,3,4,5,7,2,5,3,6,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,7,4,1,2,3,4,5,1,2,3,4,5,7,2,1,2,3,4,5]

1) Get the number of times the sequence "1,2,3,4,5" appears - in this case 7 [1,2,3,4,5,7,2,5,3,6,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,7,4,1,2,3,4,5,1,2,3,4,5,7,2,1,2,3,4,5]

2) What is the highest number of consecutive repetitions of the full sequence - in this case 3

[1,2,3,4,5,7,2,5,3,6,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,7,4,1,2,3,4,5,1,2,3,4,5,7,2,1,2,3,4,5]

Many thanks!

maybe this

M = [1,2,3,4,5,7,2,5,3,6,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,7,4,1,2,3,4,5,1,2,3,4,5,7,2,1,2,3,4,5]
Ms = sprintf('%d',M);
a = [1,2,3,4,5];
as = sprintf('%d',a);
ind = strfind(Ms,as);
qty1 = length(ind); % 7

a = (diff(ind) == length(as)); % here we see 2 consecutive ones (and we must add +1 to have all 3 values) 
                               % a = 0   1   1   0   1   0
                               % the two consecutives 1 can be identified
                               % by doing again a diff of a
                               
qty2 = 2 + numel(find(abs(diff(a))<eps)); % 3
