Hello Guys I have a matrix A that contains duplicate values in row 3,4 from column 3 to 6. I want to remove the entire 4th row, or both rows, how can i do it without using the loop?. what if i have similar problem in more rows, what's the syntax for this? I want to solve it in 1 line, help me to solve the problem. Thanks

You may have to give up the one line requirement unless you want to just string multiple lines of code together on one line, which you can do. I think you could do that with Jan's 2 line code below.

This removes all rows of the matrix Data, which have repeated values in the 3rd column. The first occurence is kept:
[C, IA] = unique(Data(:, 3), 'stable');
Data = Data(iA, :);
