Instructions:

$1.$ Create the program using MATLAB.

$2.$ Use the following code$/$program and transform it into a graphical interface $($GUI$)$:

clc;

clear;

x$=$input$(\text{'}$Enter the value of x: $\text{'})$;

y$=$f$($x$)$;

if $($y $==0)$

fprintf$(\text{'}\%$d hours of being infected.

$\text{'},$ y$)$;

else

fprintf$(\text{'}$Negative$,$ has not being infected.

$\text{'})$;

end

function y$=$f$($x$)$

if $($x$<=11)$

y$=3*$x$+36$;

elseif $((11<=$x$)$&&$($x$<=33))$

y$=$x$*$x$-10$;

elseif $(($x$<=33)$&&$($x$<=64))$

y$=$x$-6$;

else

y$=0$;

end

end

$3.$ Provide the space for the user to enter the required data and obtain the results with the printed units.
