I have a 3D matrix.

30x17x456

I'd like to select all 1st and 2nd dimention but only perticular rows in 3rd dimention.... for example

x = matrix(:,:,2:16:24:48);

This doesnt work, would i have to select each row out the matrix indavidually?

You can use a vector for the indexing. E.g.,

x = matrix(:,:,[2:16,24:48]);

Does that, or something like that, do what you want?

sorry I realised after i posted the code is wrong, im not trying to find rows 2 to 16.

I need rows:

4,16,28,40,52,64,76

Does that make sense

Cheers

This?

x = matrix(:,:,4:12:76);
