extracting subset array from a cell array

I have data with multiple values at each location x y z. I have stored this as a cell array as follows.
DataPoint{x,y,z} = [V1, V2 , V3, V4, V5, V6];
DataPoint{2,3,4}(1) works to extract the value V1 at point 2,3,4.
I want to extract the values of V1 for all the points as a 3D array.
valuesV1 = DataPoint{ :, :, : }(1);
gives the following error: "Expected one output from a curly brace or dot indexing expression, but there were 1000 results."
1) everything is numeric, is there a different structure other than cell array that would be better?
2) what is the correct syntax for this?
3) should I just make a loop to do this or would that be slower?

Use cellfun()
valuesV1 = cellfun(@(x) x(1), DataPoint);
