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