matlab如何获取路径,[转载]matlab代码中获取当前m文件所在的路径 转的

%save m-file as aa.m

function res=aa()

clc

p1 = mfilename('fullpath')

i=findstr(p1,'')

p1=p1(1:i(end))

cd(p1)

end

mfilename

File name of currently running function

Syntax

mfilename

p = mfilename('fullpath')

c = mfilename('class')

Description

mfilename returns a string containing the file name of the most

recently invoked function. When called from within the file, it

returns the name of that file. This allows a function to determine

its name, even if the file name has been changed.

p = mfilename('fullpath') returns the full path and name of the

file in which the call occurs, not including the filename

extension.

c = mfilename('class') in a method, returns the class of the

method, not including the leading @ sign. If called from a

nonmethod, it yields the empty string.

Tips

If mfilename is called with any argument other than the above two,

it behaves as if it were called with no argument.

When called from the command line, mfilename returns an empty

string.

To get the names of the callers of a MATLAB function file, use

dbstack with an output argument.
