How do I convert a .jpeg image into a .mat file?
Yes, please.
First, you can use the following command to read the .jpeg image: 
```
img = imread('your_image.jpeg');
```
And then you can use the following command to save it as a .mat file:
```
save('your_image.mat', 'img');
```
Note that the variable "img" contains the image data that you want to save. Let me know if you have any questions about this process.
