적당한 예제용 csv 파일이 있으신가요? 어떤 csv 파일을 운용중인지 알면 좋을 것 같습니다.

Hello.
I see that you have a CSV file and want to convert it to an image and save it using MATLAB.
In order to do that, please follow the steps below:
  1. You can use the "readmatrix" function to load the data from the CSV file into MATLAB. You may also want to use the additional options as a parameter to the function to ignore the column names in the CSV, if any. Here is the documentation link for "readmatrix" function: https://www.mathworks.com/help/matlab/ref/readmatrix.html
  2. Ensure that the data is normalized to the range [0, 1] or [0, 255] for image representation.
  3. Now, you can use the "imshow" function to display the image and use "imwrite" to save the image. Here are the documentation links for these 2 functions: https://www.mathworks.com/help/matlab/ref/imshow.html, https://www.mathworks.com/help/matlab/ref/imwrite.html
