Can create new environment (like new.env() in R) in MATLAB?

In R, you can create new environment by

.new_env = new.env()

as shown in here .

Can we do something similar in MATLAB?

I am trying to build different calculation environments so that I can run different m-scripts and save workspace in each environment sequentially.

Not exactly sure what you want to achieve. Do you want to save values? You could save in variables, and if you want several together you could use structures or cells that can store many variables separately.

In the same fashion as R, no.

Undoubtedly you could manage to do something to accomplish the encapsulation you're looking for, but without more specific examples of just what you envision, I think unlikely anybody here will be able to provide any specific solutions.

A simple example is something like this.

In program1.m, I want to calculate mean of first n data of X.

clc, clear
mu = mean(X(1:n));

In program2.m, I want to calculate standard deviation of first n data of Y.

clc,clear
sigma = std(X(1:n));

In doing this, I want to separately write m-script for program1 and program2, and clear variable in each code.

However, I would like to keep the settings of 'n' and 'X' in the following main.m script.

n = 10;
X = rand(100,1);
run program1
run program2

If I did not include 'clc, clear' in program1 and program 2, this code will work, but I would like to include them at the beginning.

I thought this main.m file would work if I could make difference environment for program 1 and program 2, and make both n and X accessible from both programs.

If n and X were available in the environment, then since environments have reference semantics, then "clear" would clear n and X in all of the shared references to the environment.

"If I did not include 'clc, clear' in program1 and program 2, this code will work, but I would like to include them at the beginning."

MATLAB does not have named environments like R. MATLAB scopes variables and functions by their location: https://www.mathworks.com/help/matlab/scope-variables-and-generate-names.html

Rather than writing scripts with very smelly and anti-pattern code, the best solution by far is to use functions.

Right now you have a simple choice:

1. spend quite a lot of your own time by continuing to use scripts (ugh), fighting MATLAB by adding CLEAR (ugh ugh) at the top of every script you write, and hoping for some magical way of telling MATLAB to not do exactly what you just told it to do: https://en.wikipedia.org/wiki/XY_problem https://xyproblem.info
2. use functions.

Yes, you are right. I should use function in this case. Thank you very much for your reply.
