With the bold guess, that you mean rand(100, 1) instead of rand(1:100):
data = rand(100, 1);
result = max(reshape(data, 10, 10))
% or explicitly:
result = max(reshape(data, 10, 10), [], 1)

are you looking for maximum value minus 1? If so subtract 1 from result
Or are you looking for the indices where the maximums appear? Or for the indices where the second highest appear?

@abdullah al-dulaimi: "the result will be 9 19 29 39 49 59 69 79 89 99"?
Do you mean:
x = 9:10:100
