Estimados
Ante todo gracias por leer este mensaje, estoy intentando recorrer un directorio y extraer los nombres de los archivos que estan en el mismo en un array.En otras palabras Si el directorio "G:\TesisGO\NUEVASMATRICES" contiene los archivos
"file1" ,"file2","file3", lo que necesito es extraer esos nombres en un vector
vector=[file1;file2;file3], es posible hacer esto?
muchas gracias
Walter

Esta interesante la funcion dir..... excelente explicacion

HOla
La verdad que la explicación que te dan es bastante buena, solo te falta hacerte con ella, pero rebuscando en Matlab, he encontrado un programita ya hecho que te devuelve todos los arhivos que hay en un directorio; te lo saca en un ventanita muy curioso.

\MATLAB\R2006b\help\techdoc\creating_guis\examples\lbox2.m     (lbox2.fig)
esa es la ruta.

Te mando el codigo a ver que te parece.
Espero que te sea de ayuda:

function varargout = lbox2(varargin)
% LBOX2 Application M-file for lbox2.fig
%   LBOX2, by itself, creates a new LBOX2 or raises the existing
%   singleton*.
%
%   H = LBOX2 returns the handle to a new LBOX2 or the handle to
%   the existing singleton*.
%
%   LBOX2('CALLBACK',hObject,eventData,handles,...) calls the local
%   function named CALLBACK in LBOX2.M with the given input arguments.
%
%   LBOX2('Property','Value',...) creates a new LBOX2 or raises the
%   existing singleton*.  Starting from the left, property value pairs are
%   applied to the GUI before lbox2_OpeningFunction gets called.  An
%   unrecognized property name or invalid value makes property application
%   stop.  All inputs are passed to lbox2_OpeningFcn via varargin.
%
%   *See GUI Options - GUI allows only one instance to run (singleton).

Siempre es bueno cuando a los del foro nos funciona un código, no te preocupes, siempre para servir en lo que pueda, y en mi humilde conocimiento, pues apenas estoy empezando a programar en matlab.
