Load the data into a vector and compute this average using a while loop + Using tic() and toc()

Hello, my name is Paul. I'm a beginner user in MATLAB. One of my courses assign me a problem I should use a while loop (with a text file), and tic() and toc(). Below is what I want to create.

Problem Statement

You are an electrical engineer working with renewable energy. The file ClassSDPprep_watss.txt has the maximum power in Watts required in a house for each day for the month of March. You want to compute the average power requirement for the month of March. You will need to load the data into a vector and compute this average using a while loop. Using tic() and toc() determine how long the program took to run and print the results to the screen.

I attach the text file that is needed to be calculated using a while loop as well as my attempt typing codes.

Appreciate your time and understanding.

Undefined function 'Length' for input arguments of type 'double'.
Error in Problem_3_SDP_code (line 14)
while Period < Length(Power)

MATLAB is case sensitive. Length() is considered to be different than length()
