If you want to select a number randomly from Y, you can use randi directly to index:

Y=randi([0,300],[1,500]);
RandomScalar=Y(randi(end))

RandomScalar = 266

This works because randi(imax) will generate a number between 1 and imax. The end keyword can be used to automatically determine the last position in the array.
