I have a huge temperature data with 2000 values.
It takes a couple of minutes for thermocouple to stabilize and then it increases steadily. I want to find out the position from which it is strictly increasing.
Thanks

y=[1 2 5 0 4 2 7 8 9]
%one line command
max([1 max((find(diff(y)<=0))+1)])

Walter, it's never empty, it's a concatenation [1 v], if v is empty, the result is not, max([1 v]) will be 1

pos = find( diff(YourData) <= 0, 1, 'last' ) + 1;
if isempty(pos); pos = 1; end

pos = find( [0 diff(YourData)] <= 0, 1, 'last'); %single line version
