Convert array variables names to string

Question

How to convert variables names inside array or matrix to string in matlab, so for example if I have :

variable1 = 2;
variable2 = 5;
variable3 = 6;

variables_array = {
{[variable1 variable2 variable3]}
{[variable3 variable2 variable1]}
}

how to display string like (variable names, not the values) [variable3 variable2 variable1]

Why do you want to do this? I am asking because this just smells like a bad software design decision. — Ander Biguri

I'd like to emphasise @Ander's question, because variable names should not be named dynamically. Using a struct or cell array instead is likely a better way to structure your code. — Wolfie

thanks for your notes, yes it seems not optimal from software designing point of view, but I have system with dynamic variables order, and I was wondering if there is an easy way to display the parameters name beside parameters values each time I use certain parameters subset — Adnan j

There should be no reason to avoid using a struct, then you can just output all of the fieldnames and corresponding values... — Wolfie

Just to visualize, what Ander and Wolfie suggest, and how you possibly can use that, here is small code snippet (also, have a look at how to generate field names from variables):

% Variable names (May be dynamically created by superordinate system?)
varNames = {'x', 'yy', 'zzzZZZ'};

% Values created by superordinate system
values = [1, 4.5, 22.322];

% Mimic variable and value generation of superordinate system
for k = 1:numel(varNames)
  variable = varNames{k};
  value = values(k);

  % Superordinate system should store variables and values in struct.
  sysStruct.(variable) = value;
end

% Content of struct
sysStruct

This would give the following output, which I assume is exactly, what you want!?

sysStruct =

  scalar structure containing the fields:

    x =  1
    yy =  4.5000
    zzzZZZ =  22.322
