To create: A script that will read from a file x and y data points in the following format: x 0 y 1 x 1.3 y 2.2 Year Population 1920 4021 1940 8053 1960 14994 1980 9942 2000 3385 The format of every line in the file is the letter ‘x’, a space, the x value, space, the letter ‘y’, space, and the y value. First, create the data file with 10 lines in this format. Do this by using the Editor/Debugger, then File Save As xypts.dat. The script will attempt to open the data file and error-check to make sure it was opened. If so, it uses a for loop and fgetl to read each line as a character vector. In the loop, it creates x and y vectors for the data points. After the loop, it plots these points and attempts to close the file. The script should print whether or not the file was successfully closed.
