I am trying to create a function:
FCN = @(x) x(1) + x(2);
that will accept matrix inputs and spit out a vector of values.
Ie. if the input is:
in=[1 2; 3 4], FCN(in)
the output should be: [3 7]
Is there any way of doing this? Right now, the function is only returning the sum of the first column.

FCN = @(x) x(:, 1) + x(:, 2);
sum(in, 2) % ??
