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.
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}}]
Thanks Seth.
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
Thanks Rohit ... it worked great.
