How to delete rows from an array?

Given an array of double of size 929x1, I want to obtain a reduced double array with the first 549 lines of the previous one. In short, given a double-sized array of 929x1, we want to eliminate the last 380 lines. How can I do??

Set the rows you want to delete to null. Example:

x(550:end,:)=[];
