Please, I have two coloumns of data (time and coresponding strains), I want to remove the negative values of the strains and their correponding time. I extracted the negative values of strain by x=>0. The negative values was removed successifully but the corresponding time were not.
how can I fix it. They should be equal vectors to draw them.
Thanks

Try this:
rowsToDelete = data(:, 1) < 0; % Where values in column 1 are less than 0
data(rowsToDelete, :) = []; % Delete all columns for those rows by setting to null.
% Or alternatively you can do it this way
rowsToKeep = data(:, 1) >= 0; % Where values in column 1 are more than 0
data = data(rowsToKeep, :); % Keep all columns for those rows.
