I have a 3d matrix sized 40*60*157800. I want to calculate number of values greater than 10.5 of each of the 40x60 values. This will give me a 2d Matrix of 40*60*1. I have tried this code:
sum((myarray,3)>=10.5);
But in only gives me an error. I really need help how to write this code.

result = sum(myarray>=10.5,3);

You have to sum the sums:
bothSummed = sum(myarray1>=10.5,3) + sum(myarray2>=50,3);
Of if you want both simultaneously, do
bothSet = myarray1>=10.5 & myarray2>=50; % MUST be the same size arrays.
bothSummed = nnz(bothSet);
