z(t) = x(t) * y(t) , please show calculations to get z(t) and well coded matlab code with comments for 4b and 4c

Figure Q4 x(t) y(t) 2. 1 1 -2 -1 0 1 -2 -1 0 1 2 4B. Let x[n] and y[n] be the equivalent DT signals obtained when x(t) and y(t) as shown in Figure Q4 are sampled at 10 Hz. Write a MATLAB script to compute their convolution z[n]= x[n]*y[n]. Then, provide plots of the three signals (x[n]y[n] and z[n]) by resolving the time axis back to the correct CT range from -10 s to +10 s. 4C. Write a MATLAB script to plot the expression you arrived at for z(t) from Q4. Superimpose it on the z[n] plot you obtained in Q4B. Comment on the similarities or differences with adequate reasoning
