This might not supposed to be public according to Coursera Honor Code.

Just a kind reminder. Feel free to close the issue.:yum:

You have to change line 47 to this:
X_norm=(mu)./sigma
X_mu does not exist in this code!

[licaoyuan123]

Given a new x value (living room area and number of bedrooms), we must first normalize x using the mean and standard deviation
that we had previously computed from the training set.

Which means when calculate the price, you need to use price = [1 ( ([1650 3]-mu)./sigma)] * theta; instead of line 107
