matlab - Summing a cell array? -


i have function takes in number of arguments cell array

function sumthese(varargin)  subtotals = cellfun(@sum, varargin); total = sum(subtotals);  disp(total) end

this works arrays , numbers, except have square matrix doesn't. it'll tell me:

non-scalar in uniform output, set 'uniformoutput' false.

however if set 'uniformoutput' false, error now:

undefined function or method 'sum' input arguments of type 'cell

how approach this?

change function @sum in cellfun

subtotals = cellfun( @(x) sum(x(:)), varargin );

why?
becuase output of sum, when applied matrix no longer scalar turns subtotals cell array of scalars , vectors, instead of 1d vector.

use debugger see difference.

ps,
did know cellfun not better simple loop.

edit:
solution using for loop:

total = 0; ii = 1:numel(varargin)     total = total + sum( varargin{ii}(:) ); end
