yourmatrix(any(yourmatrix, :) ==0, :) = []

To delete rows where any column is 0.

Note that by definition a vector has all but one dimension equal to 1. There can not be a vector with 2 columns and 200 rows. This is a matrix.

Also note that if it's just for plotting you don't need to delete anything. Simply use basic indexing in your plot command:

plot(yourmatrix(359:end, :));  %only plot from row 359 onwards
