MATLAB: How to assign A or B or C to a Variable

change variable name.

Hi all; I have some variables and want to change their name. For example RSxi should change to RSai then it should change to RSbi In fact at any time A or B or C will assign to x in the variable name. Please help me? what can I do? Regards

Assuming you already have a variable called RSxi, to rename it, you simply assign it to a new variable with your desired new name. Then you can clear the old variable if you want:

% Rename RSxi to RSai
RSai = RSxi;
clear('RSxi'); % If you want to get rid of old variable, clear it.

% Rename RSai to RSbi
RSbi = RSai;
clear('RSai'); % If you want to get rid of old variable, clear it.

Something like this might help:

function [oldFiles,newFiles] = splitFile(folder)
%SPLITFILE Finds files in folder, lists them and proposes new names
%   Detailed explanation goes here
dirList = dir(folder);
isDir = [dirList(:).isdir]; % to eliminate '.', '..' and any subfolders
oldFiles = {dirList(~isDir).name};
newFiles = replace(oldFiles, 'splitted_', '');
end

then use movefile to rename the files on disk.

I'm guessing you might also like to read the files into a workspace variable, where the variable name is constructed based on the source file name. One useful concept here is the associative naming for structs.

mystruct.name = readtable('myfile.txt');

works, and so also does

mystruct.('name') = readtable('myfile.txt');

This second form is quite useful here, because you can process the filename (using functions like replace() or regexp()) and use the filename to construct a fieldname that is appropriate.

MATLAB: How to update variable names after a “clear”

Unfortunately, this is a limitation of matlab's editor.

Note that

clear x

is exactly the same as

clear('x')

The former is the command form of the latter. In both cases, the input to clear is the char array 'x'.

The automatic renaming does not look in char arrays, strings or comments. So as Rik commented, the only way to deal with that is by doing the renaming yourself.

Matlab refactoring tools have thankfully improved over the years but are still way behind what is available in other editors (It really pales when compared to Visual Studio).
