New Community Feature: AI Chat Playground
Hans Scharler
on 4 Dec 2023
The MATLAB AI Chat Playground is now open to the whole community! Answer questions, write first draft MATLAB code, and generate examples of common functions with natural language.
The playground features a chat panel next to a lightweight MATLAB code editor. Use the chat panel to enter natural language prompts to return explanations and code. You can keep chatting with the AI to refine the results or make changes to the output.
Give it a try, provide feedback on the output, and check back often as we make improvements to the model and overall experience.

Not working at me why?
Write a code for the 8 cell balancing in matlab
magine a vehicle parked at cold condition. before you start the engine you have to switch a fan to heat the radiator. design a logic the thrawing process. a driver should be indicated in the dashboard
This isn't a comment on the thread topic. It's not a question or an answer. It's a copied and pasted homework assignment which is incomplete, and the portion that is available is a collage of nonsense.
I'm going to ignore whatever made you think that hiding incomplete chunks of text in random places on the internet will make your life easier. I'm more curious about whatever influenced the person who wrote this assignment.
If you need to preheat an engine prior to starting it, there's little point in heating the radiator, since it's usually thermostatically isolated from the engine. This is why block heaters exist. In any case, if the system is cold because its surroundings are cold, then how do you expect to warm it up by using a fan? If the system is so cold that it must be thawed, then the radiator and likely other components are either damaged or destroyed. As to what "a driver should be indicated in the dashboard" means, I have no idea. Could it be solved by taping a mirror to the instrument cluster?
Prompt:
draw a rectangle overlaid with an ellipse
Response:
Certainly! To draw a rectangle overlaid with an ellipse in MATLAB, you can use the `rectangle` and `ellipse` functions. Here's an example:
```matlab
% Set the coordinates and size of the rectangle
xRect = -4;
yRect = -2;
widthRect = 8;
heightRect = 4;
% Set the coordinates and size of the ellipse
xEllipse = 0;
yEllipse = 0;
widthEllipse = 6;
heightEllipse = 3;
% Create a figure and axes
figure
axes
% Draw the rectangle
rectangle('Position', [xRect, yRect, widthRect, heightRect], 'FaceColor', 'blue')
% Draw the ellipse
ellipse('Position', [xEllipse, yEllipse, widthEllipse, heightEllipse], 'FaceColor', 'red')
% Set the axis limits
axis equal
xlim([-10, 10])
ylim([-10, 10])
% Add labels and title
xlabel('X')
ylabel('Y')
title('Rectangle overlaid with Ellipse')
```
In this code, we use the `rectangle` function to draw a blue rectangle with the specified coordinates and size. Then, we use the `ellipse` function to draw a red ellipse with the specified coordinates and size. The resulting plot will have the x-axis labeled as "X", the y-axis labeled as "Y", and a title "Rectangle overlaid with Ellipse".

This calls the non-existent "ellipse" function
Prompt:
draw a superellipse
Response:
Certainly! To draw a superellipse in MATLAB, you can use the `patch` function along with the `superellipse` function. Here's an example:
```matlab
% Define the parameters of the superellipse
a = 2;
b = 2;
n = 4;
% Generate the points of the superellipse
theta = linspace(0, 2*pi, 100);
x = a * sign(cos(theta)) .* abs(cos(theta)).^(2/n);
y = b * sign(sin(theta)) .* abs(sin(theta)).^(2/n);
% Plot the superellipse
figure
patch(x, y, 'r')
axis equal
xlabel('X')
ylabel('Y')
title('Superellipse')
```
In this code, we define the parameters `a`, `b`, and `n` to control the shape of the superellipse. The `superellipse` function generates the x and y coordinates of the points on the superellipse. We then use the `patch` function to plot the superellipse as a filled shape. The resulting plot will have the x-axis labeled as "X", the y-axis labeled as "Y", and a title "Superellipse".
=====
The actual code generated is fine, but the description of it mentions a "superellipse" function multiple times; there is no "superellipse" function in MATLAB.
Prompt:
draw a square
Response
Sure! To draw a square in MATLAB, you can use the `rectangle` function. Here's an example:
```matlab
% Set the coordinates and size of the square
x = 0;
y = 0;
width = 5;
height = 5;
% Create a figure and axes
figure
axes
% Draw the square
rectangle('Position', [x, y, width, height])
% Set the axis limits
axis equal
xlim([-10, 10])
ylim([-10, 10])
% Add labels and title
xlabel('X')
ylabel('Y')
title('Square')
```
This code creates a square with a width and height of 5 units, centered at the origin (0, 0). The `rectangle` function is used to draw the square on the axes. The resulting plot will have the x-axis labeled as "X", the y-axis labeled as "Y", and a title "Square".
====
The problem is that this square is not centered on (0,0) as is claimed: it has it's lower-left corner at (0,0)
good idea
Why this feature still not available in some places , including place now ?!
Some locales are not supported by the OpenAI APIs. When they change their support, we will update ours. This is the current allowlist: https://platform.openai.com/docs/supported-countries
(1) In the code window, the previous test codes should be removed automatically, or those codes which have already been compiled should not be compiled and refresh again; (2) We can not interact with the figure produced by the codes. For example, we can not change view of 3D figure. (3) We can not have a timely view of each step of figure/command window, but only see the final results. (4) Maybe add more buttons like upload and analysis matlab codes/debug/improvement suggestion...
Great suggestions. Thanks for sharing your feedback!
