I have a matrix 101x19, I want to flip each column upside down to turn peaks in valley:
How I can do a loop?
for i=1:length(data);
Flipdata(i,:) = 1.001*max(data,i-1)-(data,i);
end

for i=1:size(data,2)
Flipdata(:,i) = 1.001 * max(data(:,i)) - data(:,i);
end
or, with no loop,
Flipdata = repmat(1.001 * max(data), size(data,1), 1) - data;
and if you have R2016b or later
Flipdata = 1.001 * max(data) - data;
