A = randi(10,1,15)
CountIf = numel(A(A>5))
gives:
A =
9 7 4 10 1 5 4 8 8 2 5 5 7 8 8
CountIf =
8

Another way is to take advantage of the fact that logical in MATLAB has the value of 1 for true, and 0 for false.
So, using sum function would gives the same result as the previous answer of using numel; i.e.:
A = randi(10,1,15)
CountIf = sum(A>5)
gives:
A =
9 7 4 10 1 5 4 8 8 2 5 5 7 8 8
CountIf =
8

The best way to perform the equivalent of a COUNTIFS function in MATLAB is to first convert your data into a table and then use the GROUPCOUNTS function. Details: https://www.mathworks.com/help/matlab/ref/double.groupcounts.html
