Assuming you intended to put spaces or commas between the numbers, use the sum function:

x=[3,7,2,9,4];
sum_x = sum(x)

No inversion is necessary. Just reverse the sign of the > sign if you want to find maximums that have values the opposite of what you'd normally think they should have.

% Threshold to get dark values, which are max saliencies for both arrays.
maxVisual = VISUALSALIENCY < 128; % or whatever

maxEvent = EVENTSALIENCY < 128; % or whatever
bothMax = maxVisual & maxEvent; % If you're interested in where both are max.
