NPollutants from fertilizer, pesticides, vehicular traffic, chemical spills, etc. can affect pH and bacterial levels in the soil. A large track of land is being monitored by using robotic devices to take measurements of pH and bacteria levels. These measurements are being saved so results can be analyzed over time. The samples will be taken at regularly spaced intervals. For simplicity, a grid shown (20 rows, 20 columns) could represent the track of land:

As a coop student working for the company contracted to do the analysis, your job is to create two prototype programs: one in C++ and one in MatLab to show how the team could track and analyze results.

C++ Program

There are 3 input files that you will need to handle:

NewdataB.txt - New data from a recent sampling: pH and bacterial (B2) levels together. This single file has pairs of data (the 1^st is pH, the 2^nd is B2) for each location on the grid. (Hint: this will mean 20 rows and 40 columns of data.)

HighpHB.txt - Summary data from all prior samplings = highest pH levels at each grid location.

LowpHB.txt - Summary data from all prior samplings = lowest pH levels at each grid location.

Your boss is an environmental engineer but has some background in programming and has suggested the following steps and functions for your program:

Read in the data from the data files into 2D arrays, Newdata.txt, HighpH.txt and LowpH.txt.

One function to sort the new data, i.e. separate out pH measurements from B2 (bacterial) measurements. These files should be named: B2B.txt and pHB.txt.

Function to compare the new data (pHB) to the 2 summary data files (HighpHB.txt and LowpHB.txt). It should replace the summary data if there is a new maximum pH or new minimum pH detected at that position on the grid.

Then in a function or in main, write out two new data files with the new pH data and the new B2 data.

Note: this is a prototype only for pH. In the future, the analogous bacterial file functions would be developed.

MatLab Program

The MatLab program will only analyze and graph two of the data files (the others will be left for a future coop student to handle). The program should read the B2B.txt and pHB.txt files into MatLab. It should then:

Find the average pH for all of the data in pHB.txt and display it using a fprintf statement.

Find the maximum pH and minimum pH for all of the data in pHB.txt and display them using a fprintf statement.

Find the average B2 level for all of the data in B2B.txt and display it using the fprintf statement.

Find the maximum B2 and minimum B2 for all of the data in B2B.txt and display them using the fprintf statement.

Produce 3 graphs:

3 dimensional graph showing pH levels by location on a 20x20 grid. Recommend using a mesh plot of pH.

3 dimensional graph showing B2 levels by location on a 20x20 grid. Recommend using a mesh plot of B2.

pH vs. B2. Recommend plot(pH(:), B2(:), .)

Note: all of above graphs must have appropriate titles and axis labels.
