delete repeated times from matrix

Hello! I have a matrix of times and irradiance values. It seems that some of the times (itime) must be duplicates.

length(unique(itime)) = 44850

length(itime) = 44858

I would like to find those 8 times that are not unique and remove the repeated times and the corresponding irradiance value (irrad). I don't want to keep any time that is repeated since there is no way to determine the correct irradiance value for the timestamp. I've attached the mat file with itime and irrad if that helps.

Thank you!

[unique_itime, Aidx] = unique(itime, 'stable');
corresponding_irrad = irrad(Aidx);
