to_s(fmt=nil, coljoin=', ', rowjoin='; ')

Convert this matrix to a string.

This methods takes a few extra arguments to control how the result looks like.

fmt is a format as used by sprintf, coljoin is the string used to join column, rowjoin is what is used to join rows. For example,

   x.to_s('%.1f', ' ', "\n")

Returns a matrix where columns are separated by spaces, rows by newlines and each element is shown with one digit after the comma.
