Matlab实用函数

 1 : filesep

   Directory separator for this platform.

    F = filesep returns the file separator character for this platform.

    The file separator is the character that separates

    directory names in filenames.

Example(windows): 

filesep

ans =

\

2:  fullfile

    fullfile(D1,D2, ... ,FILE) builds a full file name from the directories D1,D2, etc and filename FILE specified. This is conceptually equivalent to

       F = [D1 filesep D2 filesep ... filesep FILE]

    except that care is taken to handle the cases where the directory

    parts D1, D2, etc. may begin or end in a filesep. Specify FILE = ''

    to build a pathname from parts. 

Example(windows):

fullfile(matlabroot,'toolbox','matlab','general','Contents.m')

ans =

C:\Program Files\MATLAB\R2011b\toolbox\matlab\general\Contents.m
