$[5$ points$]$ The file temp$\_$cal.mat contains the matrix variable $x$ which has the output of a

temperature transducer in the first column and the actual temperature in $C$ in the second

column. The transducer is known to be linear. The file temp$\_$out.mat is the output of this

transducer over a $2-$day period. This output is in variable y and is sampled every $1$ min $.$ Write a

MATLAB program to take the data in temp$\_$out.mat and plot actual temperature in $C$ as a

function of time. The horizontal axis should be in hours. Correctly label the axes, as should be

done for all MATLAB plots. $[$Hint: First find the equation for this transducer system that is

equivalent to Equation $2\mathrm{.}1$ by plotting column $1$ against column $2.$ Note that, unlike the transducer

described by Equation $2\mathrm{.}1,$ the transducer in this problem does have an offset; that is$,b$ in

Equation $2\mathrm{.}2$ is not $0\mathrm{.}0.$ Use this equation in your program to decode the data in temp$\_$out.mat

and then plot using an appropriate horizontal axis.$]$
