Here i have a 1X6 matrix
y =
682.8333 399.8160 34.2270 46.1800 107.7035 21.5367
what i wanna do is to find the FIRST minimum element
which means if i plot "y" i wanna find first minimum turning point
for this example it must be 34.2270
Thank you.

pks = findpeaks( -y );
will work if you have the Signal Processing Toolbox.
If you don't you can find peak finding algorithms on the File Exchange that will do a similar job.

y = [682.8333 399.8160 34.2270 46.1800 107.7035 21.5367];
out = y(find(diff(y)>0,1,'first'));

This only works if it is a decreasing function for the first values of y...
