How to delete multiple rows of particular values?

I have a matrix of 56298 x 15. Each column has a different header such as;

'UTC, startSeconds, duration...'

I am wanting to remove entire rows (for all columns) if the 'startSeconds' is equal to or lower than 2.37.

I've tried the 'find' function but I'm concerned that will only delete the value of the cell

What exactly is your "matrix"? A cell array? A table? Or ...?

Hi James,

It's a csv file imported as a table

Assuming that the variable is a matrix and the second column is startSeconds

rowstokeep = data(:,2) > 2.37;
data = data(rowstokeep,:);

For a table you can change the first line

rowstokeep = data.startSeconds > 2.37;
data = data(rowstokeep,:);
