Hello everyone,
I have let's say : x=' a name' ; and B= [1 2 3],
and I want to create a variable ' a name' = B whiche is [1 2 3], in another word i want to create a variable using the string of another variable (example filename='Hallo' the 'Hallo'= B=[1 2 3],
So, I tried to use [x]=B; but it does not work;

actually, I read many csv data and concantae them in one matlab table then i have to save as the specfic name :
for example: dir()
all_table=[] % concatenate all csv files
for i=1:numel(files);
R= readtable((files(i).name));
all_table=[all_table;R];
save (all_table, 'standard_name') % mast save as mat file because i exceeded 2^20 ( the limit of exporting an excel file) but this command does not include an option to save the file with desired name.
:D

@Ayman Mounir: your save usage makes no sense.
The first input argument of save must be a filename, so why are you providing a table as the first input?
The second input is usually the name of the variable to be saved, it is not clear what you expect the character vector 'standard_name' to achieve. I recommend that you read the save documentation, it explains how to use save.
In any case, magically defing variable names is unlikely to be a suitable solution to ... whatever you problem might be.

thanks, but without creating a structure

The MATLAB approach:
N = numel(files);
C = cell(1,N);
for k = 1:N
F = fullfile(files(k).folder,files(k).name);
C{k} = readtable(F);
end
dataname = vertcat(C{:});
save('some_file_name.mat', 'dataname')
