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)
