lab_he(:, :, 2:3)
is the [M x N x 2] subarray taken from the [M x N x P] array called lab_he. double() converts it to the type double.
These are elementary Matlab methods. If is not efficient to ask such general and basic questions in the forum. Better read the "Getting Started" chapters of the documentation to learn how to use this powerful language.
