Answer 1

Please use the code format button {}Code rather than putting spaces between each line.

A matrix can only contain numbers, colons are not allowed. If it's only for display that you want that, there's no simple way to force matlab to display matrices like this.

Possibly, you can convert the matrix into a table and assign names to the rows:

m = [1 0;0 2; 2 1; 0 3; 3 2; 2 0; 4 1];
t = array2table(m, 'RowNames', sprintfc('%d:', 1:size(m, 1)), 'VariableNames', sprintfc('col%d', 1:size(m, 2)))

Otherwise, you'll have to write your own display function which is far from trivial if you want it to play nicely with format.
