The following two options affect the display of all matrices.
Format rat matlab.
Matlab always displays integer data types to the appropriate number of digits for the data type.
Format rat uses a continued fraction algorithm to approximate floating point values by ratios of small integers.
The rats function calls rat and returns strings.
To maintain a format across sessions choose a numeric format or line spacing option in the command window preferences.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
All computations in matlab are done.
The rat function attempts to do this.
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.
The result is an approximation by continued fractional expansion.
To see which type is currently in use type.
To maintain a format across sessions use matlab preferences.
See rat m for the complete code.
Matlab always works in double precision unless you are using the symbolic math toolbox but output display can be changed with the format command.
For example with the rat format pi is displayed as 355 113.
The result is an approximation by continued fractional expansion.
You can insert a space between short or long and the presentation type for instance format short e.
The specified format applies only to the current matlab session.
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.
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.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
Remove blank lines around column number labels and between matrices producing more compact output with more data per page.
From the matlab prompt help format format set output format.
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.
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.
