How can I change the elements of a list, say on positions
{{1, 4}, {3, 1}, {2, 3}, {4, 4}}
in one go?
Take this list for example:
In:= (m = Array[RandomInteger[9] &, {4, 4}]) // TableForm
Out= 0 6 2 8
3 8 8 0
3 7 4 1
4 8 2 4
This is how I want to the elements on the specified positions to change.
m[[1, 4]] = Style[m[[1, 4]], 14, Bold, Blue];
m // TableForm
The result is that the 8 in the last element of the first row is now blue and bold (and bigger to stand out).
