How to run .m file automatically without path?

Dear all,

I have .m file for starting up program. I always have to put (write) the path this .m file. For example: run C:/Program Files/.../file.m. I would like to automatized this action for any PC, without using file path. Is this possible in Matlab?

Thank you for your answers.

If you don't specify the path to the file, it will have to be in one of the folders on the matlab search path for it to be found. See this page for the folders that are in the search path.

Okay, concretely I have this path for startup program Eidors:

run C:/Users/ced0005/eidors-v3.8-ng/eidors/startup.m

And I would like to automatized this link of code. How can I do it? Thank you.

If the folder C:/Users/ced0005/eidors-v3.8-ng/eidors/ is on the matlab search path your startup file will be executed automatically.

If it's not, you have several options as detailed in the page I linked:

• Permanently change the user home folder with userpath, so

userpath('C:/Users/ced0005/eidors-v3.8-ng/eidors/');

• Add the folder to the environment variable MATLABPATH, if the variable does not already exist (most likely), then at windows command prompt:

set MATLABPATH="C:/Users/ced0005/eidors-v3.8-ng/eidors/"

• Add the folder to the search path using either the GUI tool or with addpath and savepath

Okay, but will it works on other computers, where the program eidors has a different path?

[Guillaume]

Well, it all depends how you get that program onto other computers. If you use an installer, then either that installer needs to add the folder where it's put to the matlab path, or it needs to put the file(s) in a folder already on the matlab path.

If you copy the program manually, then it's up to you to do the same.
