MATLAB

Suppose that a file named sensor$.$dat contains information collected from a set of sensors$.$ Each row contains a set of sensor readings, with the first row containing values collected at $0$ seconds, the second row containing values collected at $0\mathrm{.}5$ seconds, and so on$.$

Load the data file.

a$)$ Read the data file and print the number of sensors and the number of seconds of data contained in the file. Use the size function$-$don't just count the two numbers. $-$ call your result num$\_$sensors

b$)$ Find both the maximum value and the minimum value recorded on each sensor and use MATLAB to determine at what times they occurred. Create an array called max$\_$time that contains the time when the maximum occurs for each sensor in column $1,$ and the corresponding temperatures in column $2.$ Create a similar array called min$\_$time for the minimums.

c$)$ Find the mean and standard deviation for each sensor and for all the data values collected. Your result should be vectors named sensor$\_$means and sensor$\_$stds$.$

d$)$ Find the overall mean for all the sensor readings. Name your result overall$\_$mean.

e$)$ Find the overall standard deviation for all the sensor readings. Name your result overall$\_$std$.$
