Hello,
I have a data array like:
x = [0, 0, 45, 43, 42, 41, 0 , 0 , 0, 0, 45, 43, 42, 41 ];
In my data points, 2 times my data became non-zero. Which I call them an "event".
I want my code to calculates the number of events as "2".
and calculate the sume of numbers at each event.
I'd appreciate your help at this matter.
Thanks,

Try this (requires the Image Processing Toolbox, which you probably already have):
x = [0, 0, 45, 43, 42, 41, 0 , 0 , 0, 0, 45, 43, 42, 41 ];
% Count number of non-zero regions: (requires Image Processing Toolbox)
[~, numNonZeroRegions] = bwlabel(x)
% Compute sum of values
props = regionprops(x>0, x, 'PixelValues');
sumOfValues = sum(vertcat(props.PixelValues), 2)
