Creating Vector using MATLAB

"Create a 3044 x 1 vector containing the mean value, for each gene,

from the Day 0 samples. In other words, this creates a 3044 x 1 vector

from a 3044 x 3 array, with each row containing the average of 3

measurements. Hint: the function mean usually operates column-by-column,

but it can be told to operate row by row. In other words, the commands

mean(X,1) and mean(X,2) will produce different results."
