Sum of defined portion of a 3D matrix

Hello,
I would like to sum different layers of a 3D matrix, but I don't know an easy way of doing it. Basically what I would like to do is this:
matrix1=sum(timematrix(:,:,1:3))
"timematrix" is a 1x1000x5 matrix and I would like to compute the sum of the first 3 layers. Using the following command works:
matrix1=timematrix(:,:,1)+timematrix(:,:,2)+timematrix(:,:,3)
Thanks in advance!

matrix1 = sum(timematrix(:,:,1:3), 3);
