I have several columns in a cell array A with double values, and I am applying this very simple formula to get separate variables:
y=cell2mat(ANALLSper(:,2)); %for example
And for somecase ist gives me this error:
Error using cell2mat (line 45)
All contents of the input cell array must be of the same data type.
Does someone know how to solve it? Thank you very much.

It means that not everything in that array is what you think it is. Try looking at that array in the editor.

Check it manually:
all(cellfun('isclass', ANALLSper(:,2), 'double'))

Maybe you don't even need a cell array. Why deal with that complication if you don't have to and you ultimately want to get a double array anyway. Why not just start off using a double array. A cell array is more flexible but more complicated. If you really want the complication of a cell array, read the FAQ: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
