Count number of values greater than a certain value in 3d matrix

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);

Thanks. What can I then do if I want to count two matrixes greater or equal to certain values. I want matrix one greater than 10.5 and at the same time matrix two greater than 50. I have tried this:

sum(myarray1>=10.5,3 & myarray2>=50,3);

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);

@Espen: You almost had the syntax correct:

sum(myarray1>=10.5 & myarray2>=50,3)
