The result is an approximation by continued fractional expansion.
Format rat matlab.
Matlab always works in double precision unless you are using the symbolic math toolbox but output display can be changed with the format command.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
For example with the rat format pi is displayed as 355 113.
The following two options affect the display of all matrices.
To maintain a format across sessions use matlab preferences.
The specified format applies only to the current matlab session.
See rat m for the complete code.
N d rat x tol returns n d approximating x to.
Los formatos numéricos sólo afectan a cómo aparecen los números en la salida de la ventana de comandos no cómo matlab los calcula o guarda.
All computations in matlab are done.
Format por sí mismo restablece el formato de salida al valor predeterminado que es el formato corto decimal fijo para la notación de punto flotante y el espaciado de líneas sueltas para todas las lineas de salida.
The specified format applies only to the current matlab session.
To see which type is currently in use type.
If you consider the first two terms of the expansion you get the approximation 3 1 7 2 2 7 which only agrees with pi to 2 decimals.
N d rat x returns arrays n and d so that n d approximates x to within the default tolerance 1 e 6 norm x 1.
You can insert a space between short or long and the presentation type for instance format short e.
The rats function calls rat and returns strings.
Remove blank lines around column number labels and between matrices producing more compact output with more data per page.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
The rat function attempts to do this.
To maintain a format across sessions choose a numeric format or line spacing option in the command window preferences.
If you consider the first two terms of the expansion you get the approximation 3 1 7 2 2 7 which only agrees with pi to 2 decimals.
The result is an approximation by continued fractional expansion.
Rational approximations are generated by truncating continued fraction expansions.
