Solution

let you know about the program as below

clc

clear all

t=0:1:40

y=5*cos(30*pi*t+0.25*pi)

sub plot(2,1,1)

plot(x,y)%CT

title(\'CT cos wave\')

grid

subplot(2,1,2)

stem(t,y) %DT

title (\'DT cos wave\')

grid

notes

plot(x,y) : is used for CT continuous signals

stem(x,y): is used for DT discrete signals

or else go for this method adding a MATLAB function block to a model

1. create a new simulink model and add a MATLAB function block to the model from the user-defined functions library.

2.add source and sink blocks

3. from the source library, add a constant block to the left of the MATLAB function block and set its value to vector like[2 3 4 5];from the sink library,add two display blocks to the right

4.in the simulink editor,select File> save as and save the model as call_stats_block1.

programming the MATLAB function block

1.open the call_stats_block1 model .double click on it to open to edit

2. edit the function header line

function[mean.stdev]=stats(vals)

3.save the model as call_stats_block2

4.complete the connections between the blocks

5.now edit functional blockand save it

checking for errors

1.change the default complier to mex-setup

2.open the call_stats_block 2 and double click on it for editing

3. in MATLAB functional block editor,select build model.build to compile and build the example.
