Detect Keyboard Input Matlab

  I have a simple question, although it's harder than it seems; I couldn't find the answer on the interwebs :O I'm writing a script in Matlab. What I want to do is the following: When I press the esc key, I want a helpdialogue to pop up, so my script pauses. (So when I press esc, I want to stop the whole script to run so that the car (which im writing the script for) stops driving) How do I do this? How can I say to Matlab: When I press esc, do this... Thanks for your time guys! EDIT: It's no option to implement something which awaits the keypress. Im writing a script for a driving car. It just has to drive around basically, but when I press esc for example, it should stop driving. So the script just has to run, untill I press the esc key; then the script has to pause.

What is difference between stem and plot in MATLAB?

 Both plot and stem functions are used to represent a curve in MATLAB.

The main point of difference between the two is that plot displays the continuous values for the curve. Think about drawing a graph of y= sin(x) using a pencil without removing its contact from paper.
On the other hand, stem displays the discrete values of the points on the curve. Think about drawing the graph of y=sin(x) for specific values such as 0,15,30,45,60and 90degrees respectively. Then join these points from the X-axis. This is the result given by stem.
Try to run this simple code on MATLAB to find the difference yourself.

clc
clear all
close all
x = linspace(-pi,pi,50);
y = sin(x);
subplot(1,2,1)
plot(x,y)
xticks([ -pi 0 pi ])
xticklabels({'-\pi','0','\pi'})
title('Plot function of Sin(x)')
grid on
subplot(1,2,2)
stem(x,y)
xticks([ -pi 0 pi ])
xticklabels({'-\pi','0','\pi'})
title('Stem function of Sin(x)')
grid on

The output of this code:

In the code, I’ve used linspace to give the range and the division of values. I’ve used subplot to divide the area of of figure window into 2 equal parts. I’ve also used xticks and xticklabels to change the X-axis from number format to π format. I’ve used other features such as title, grid on to make my curve presentable.

You can clearly see that the curve using plot displays a continuous line while the use of stem results in discrete values marked on the graph.

What are some good alternatives to Simulink?

Matlabsolutions provide latest  MatLab Homework Help, MatLab Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. SIMULINK is a visual programing environment specially for time transient simulations and ordinary differential equations. Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model right in the GUI and with
