Comparing elements in a 2d array

I would like to know if it is possible to find the peak numbers, numbers that are larger then the value befroe and value after. Thank you in advance

array = [1 2 1 3 4 6 4];
peak = 0;
for i = 1:length(array)
    if array(i) > array(i)-1||array(i)<array(i)+1
        peak = peak + 1;
    end 
end 

disp(peak);

>> peak = [0, diff(array(1:end-1))>=0 & diff(array(2:end))<=0 , 0]

peak =

     0     1     0     0     0     1     0

>> array

array =

     1     2     1     3     4     6     4
