I am using the free version of the Wolfram Alpha Mode Notebook. In it I have an 11 x 11 matrix and I would like to shade a sub-matrix, 4 x 4 sub-matrix, within the 11 x 11 matrix.
Could you please point me to an example or some documentation that illustrates how this is done.
Thanks.
Thanks Rohit ... it worked great.
Thanks Seth.
If you are willing to wrap your matrix in Grid, you can do something like this:
Grid[RandomInteger[{1, 8}, {11, 11}], Background -> {None, None, {{{4, 7}, {6, 9}} -> LightRed}}]
You could try applying a Style to the elements
Style
SeedRandom[123]; r = RandomInteger[{1, 8}, {11, 11}]; MapAt[Style[#, Red, 16] &, r, {4 ;; 7, 6 ;; 9}] // MatrixForm
