3)a) Draw the given function in the MATLAB command line by following the steps below. 1. Time vector >>t=0:0.1:10; produced by the command. 2. For example, if the desired function is t x t te− ( ) =...

3)a) Draw the given function in the MATLAB command line by following the steps below.
1. Time vector
>>t=0:0.1:10;
produced by the command.
2. For example, if the desired function is t x t te− ( ) =
>>x=t.*exp(-t);
With the command x vector is obtained.
3. To plot x against t
>>plot(t,x)
command is used.
4. To write axis information on the drawing
>> grid on;
>> xlabel('t(time)');
>> ylabel('x(amplitude)');
>> title('graph of x(t)');
