Hi, so for example I have P such that: P =
3×1 cell array
[1]
[2]
[3].
The matrix P can be a n x 1 cell array, where n is any positive integer, and can only hold numbers. Ive tried to sum these numbers using sum(P) but keep getting the error ' Undefined function 'sum' for input arguments of type 'cell'. '. Any ideas on how I could do this? thank-you.

@Gian Carpinelli: why are you storing numeric data in a cell array? It would be simpler to store it in a numeric array.

sum([P{:}])
But why would you store it in cell array? If they are all numeric, better use a numeric array.

You can use either
sum(cell2mat(P))
or
sum([P{:}])
