Question
This assignment will help you understand how for loops can be used to accomplish tasks that would otherwise require extensive time and would stress Excel’s capabilities. Coding Constraints: You may not use reshape() to solve Part 1 or 2. You must use FOR LOOPs. However, you may use embedded MATLAB syntax to check your answer. PART 1. Reorganize weather station measurements into column format The readings from a weather station in Los Angeles outputs average daily measurements of atmospheric variables. The weather station file WS_2010.txt includes the year, month, day, Temperature [K], Relative Humidity [%], and Surface pressure [Pa], in that order, in one single row. There are 365 days of observation. For example: 2010 1 1 286.90 62.88 101768.180 2010 1 2 286.64 61.62 101746.805 2010 1 3 286.38 61.05 101754.727 2010 1 4 286.41 63.31 101779.648 2010 1 5 286.67 … The numbers above in bold/red are the date values followed by the atmospheric readings. Use FOR LOOP(S) syntax to separate the daily values into a six column matrix. There are several ways to perform this analysis. Save this matrix to a file called “LA_climate_2010_columns.txt”

A=csvread('WS_2010.txt');
