Is there any similar to AStyle formatting tool for C/C++/C# languages which can beautify matlab m-file code?
Ctrl+I is too simple for my needs

To answer this, we have to know your needs.
Personally I prefer an indentation, which is as trivial as possible - simply eye-popping.

the same as in AStyle
to convert some unreadable or unformatted code to uniform style
example:
[V,D]=eig(Kn);clear Kn;
V=sortrows([V' diag(D)],size(X,1)+1);V=flipud(V);
latent=V(:,end);
coeff= V(:,1:end-1)';
clear V;clear D;
to uniform:
[V, D] = eig(Kn);
clear Kn;
V = sortrows([V' diag(D)], size(X,1)+1);
V = flipud(V);
latent = V(:,end);
coeff = V(:,1:end-1)';
clear V;
clear D;

I know it is an old question, and I just put this here as an addition.
You could check: MBeautifier
I have just created it for personal use, it is a lightweight M-Script based tool that can be usable to format Matlab M-Code directly in the Matlab editor

Yes, that's exactly what I want, very useful!

Great tool!
Just some remarks: * It doesn't seems to take parameters file into account, you have to cange rules directly in the code of MBeautyConfigurationRules.m. * Sometimes it doesn't recognize tokens, for instance "A(j-1)" is correctly beautified as "A(j - 1)", but "A{j-1}" is not. * Sometimes it adds empty lines at the beginning and at the end of the file, I didn't found any rule when it does. * I didn't found an option to indent the whole function's body (it is the default behaviour of Matlab not to indent, but I prefer to indent)
Nevethenless, it's a great tool which saves me a lot of time! Thanks again!

That feature (to pad tokens inside { } exists in the xml settings near the bottom.
To indent a whole function's body you need to set that in the smart indenting settings of matlab itself.
see here:
Keep your code readable with smart indenting
Set to INDENT ALL FUNCTIONS

Hi David,
I know I am very late to this, but I don't really know how to add the root directory to my matlab path as you describe on the github page...
I also don't understand how to do the shortcuts part.
Could you (or someone else) help me with this?
Thanks in advance!
Ruben

I know this question is quite old, and there is already a solution for Maltab GUI Editor. However, I prefer to edit M-files with vim, I'm frustrated to find that there was no a proper solution for commandline usage. So I imlement one using C++, which achieve quite simple formatting. The code is available on Github https://github.com/TroyDanielFZ/Matlab-M-Source-Formator .
This answer is posted in case that someone else need this implement for editors like vim.

vscode has a pretty good matlab formater built in (formats on save). Underpinning the vscode plugin is a python script which you can run on the command line (matlab_formatter.py <matlab_file_name>)

Did you try the "Crimson Editor" or XEmacs already?

I don't understand why control-I is not acceptable for you and Yuriy. What's wrong with the way it does it? It fixes the indenting, though it doesn't add spaces around operators such as = and +. Is that the problem?

Because indentation is not enough for beauty code.

Here's a MATLAB snippet that depends on the undocumented tree2str and mtree, but produces a reasonable result:
tree2str(mtree(FILENAME, '-file', '-comments'))
