MATLAB Permission

Hi,

I am receiving an error while trying to save a file. I have entered:

A=[34,45;17,6]
save A1.dat A -ascii

I am receiving

??? Error using ==> save

Unable to write file A1.dat: permission denied.

I just installed MATLAB and do not know how to grant myself permission to write the files.

There is no need to enable saving or so. This will be just related to the directory / folder you attempt writing to. Mostly, this is when you have a directory within yout MATLAB installation. Try a different directory. If difficulties persist, let us know the OS, the MATLAB release and the directory name.

I have been able to save the .dat file as a .m file in a seperate folder from the editor. When I run the code, I get my matrix as coded, followed by that error. But I need to be able to save the code as denoted for my class in order to submit my code for assignments. OS Window's 7

MATLAB 7.12.0(R2011a) I am not sure what you mean by directory name. I am new to MATLAB and using it for a class.

[Andreas Goser]

"directory name" is with relation to the operating system. In MATLAB, you get the "current directory", e.g. by using the PWD command, or you see it at the top of the IDE. If yoo copy that string into the Windows Explorer, then you can check permissions. If it is below the MATLAB installation path, you should chosse a different directory for saving data.

Thanks Andreas ,this worked for me

Sounds like you're using a school's computer, and appearently you lack the permission to write to the MATLAB directory.

Try saving to a USB memory stick, or the My Documents folder.

use this command with file name getinet.mat

save(fullfile(tempdir, 'getinet.mat'))

and to load a file with file name getinet.mat

load(fullfile(tempdir, 'getinet.mat'))

have a nice coding with great day

Be careful, though: if you are using a shared computer, then the systems administrator might delete the contents of the temporary directory at any time. Also, some operating systems delete the temporary directory files each time the system reboots.

In Windows,

1) you need to open matlab as administrator, if you are admin.

2) create the folder and check if the path fully exists.
