A is a column vector. I want a small one-line code/command to delete only 2nd, 5th and 8th rows of A simultaneously. Basically I want to delete those rows in one go/ one run.

在 MATLAB Online 中打开

ARRAY(ARRAY==VALUE) = []; %delete if array is exactly value

or

NEW_ARRAY = ARRAY(ARRAY~=VALUE) %create new vector without disturbing old one

or

ARRAY(ismember(ARRAY, [LIST OF VALUES])) = []    %delete if value is any of the ones in the list of values
