Matlab - Eliminar solo filas aleatoriamente y crear nuevas matrices desde una matriz original.

Val: 23

Eliminar solo filas aleatoriamente y crear nuevas matrices desde una matriz original.

Publicado por Nick (14 intervenciones) el 02/11/2018 17:10:34

Buenos días tengo un archivo(matriz), el cual adjunto, para generar nuevas matrices de misma columna(no cambia, que se mantengan) pero extrayendo solo filas (es decir extraer aleatoriamente), necesito crear un script en matlab que cree nuevos archivos (matrices) en txt, al menos 100 archivos nuevos, obviamente de menor valor en filas pero la misma cantidad de columna.

Esta es mi matriz original, tambien la he adjuntado en un zip:

Eliminar solo filas aleatoriamente y crear nuevas matrices desde una matriz original.

Publicado por JOSE JEREMIAS CABALLERO (5917 intervenciones) el 02/11/2018 17:36:24

clear all,

 M=importdata('ESTinvierno_01_DHN0612.txt');

cantidad_de_matrices=4;

for i=1:cantidad_de_matrices

    r = unique(randi([1,size(M,1)],1,size(M,1)),'stable')';

   v=genvarname(['V',num2str(i)]);

   eval([v,'=M(r,:)']);

end

Muchas gracias por tu consejo estimado José, una última consulta, si deseo guardar esos 4 archivos como un txt es decir:
Si el original es ESTinvierno_01_DHN0612.txt que los demas archivos sean

ESTinvierno_01_DHN0612_caso1.txt
ESTinvierno_01_DHN0612_caso2.txt
.....
....
ESTinvierno_01_DHN0612_cason.txt

utilizo dlmwrite o save dentro del bucle?

Disculpa mi ignorancia Jose, intente con ello y no me sale, serias tan amable de indicarme mi error
dlmwrite(['V',num2str(i)], v ,'precision','%13.6f','delimiter',' ' );

Gracias
