How many rows and columns and color channels are in the "image"?

I think it is a grayscale image and the text file consists of simulation measurement data of pixel intensity values. This txt file is an output Of simulation. The file has a resolution of 1392 by 1040.

You can use the following function to read a txt file.

readmatrix, readtable, load etc

Example:

data=readmatrix('post_mathworks.txt');
imshow(data);

%or

imshow(uint8(data));

%or

imagesc(data);

Please refer the MATLAB Docs to read about different functions.

Please ensure that the text file in the proper arrangement and alignment of all data elements. You may need to avoid 2 or 3 lines to avoid any headers associated with the file.

Notice the large number of dots in the image. All about how you represent the data (data type)
