Read data from a file.
Write data to a file
Plot data.

This function wijll read the text file called "filename" in the same format identified above for result slixt ¥ and results2.txt 1 . From that data it will create a cell array "data" variable which will have the following structure... { {char array} {uintie} {double} {double} {double} {double} {double} {double} {double} {double}; {char array} {uint16} {double} {double} {double} {double} {double} {double} {double} {double}; {ever array} {uinti6} {double} {double} {double} {double} {double} {double} {double} {double} } o Each cell array row represents another row read from the file. The cell array columns are "ObjectName, Velocity, Distance1, Distance2,....Distance8" in that order. "readDataFile" will return this cell array, "data". = For example... >> example data = readDataFile('example data.txt') example data = 2x10 cell array Columns 1 through 5 {'Objectl'} {[1001} {1.10001} {[1.2000]} {[1.30001} {'Object2'} {[2001} {2.10001} {[2.2000]} {[2.3000]1} Columns 6 through 10 {[1.40001} {[1.50007}% [1.600011 {[1.70001} {1.80001} {[2.4000]} {2.50001} {[2.60001} {[2.70007} {[2.80001} >> >> cellplot (example data); $%save to example cellplot.png And the distance range it traveled “r" is... r=wvx"'t You decided to test these equations by running experiments with a "tennis ball”, a "base ball", and a "lead ball" over several initial velocities and angles. You collected data and saved iti in two files resultsl.txt ¥ and results2.txt | . In these files, each row is formatted as.. (objectName Velocity Distancel Distance? Distance3 Distance4 DistanceS Distance6 Distance? Distances where"ObjectName" is the name of the object throw, "Velocity" is the initial velocity of the object, "Distance" is the distance that object travel thrown at that velocity at an angle of "10", “Distance2" for at an angle of "20", .. .,» and "Distance8" for at an angle of 80. ObjectName is a single word. Velocity is a positive integer. Distancel-8 are floatin is separated by a single space and each row is terminated by the '\n' character. 8. pointumbers.
