is used to print elements of the matrix
In addition, x04cfc
chooses its own format code when form
- x04cfc will choose a format code such that numbers will be printed with either a %8.4f, a %11.4f or a %13.4e format. The %8.4f code is chosen if the sizes of all the matrix elements to be printed lie between and . The %11.4f code is chosen if the sizes of all the matrix elements to be printed lie between and . Otherwise the %13.4e code is chosen.
- x04cfc will choose a format code such that numbers will be printed to as many significant digits as are necessary to distinguish between neighbouring machine numbers. Thus any two numbers that are stored with different internal representations should look different on output.
