How to store variable name AND value in an array?

Suppose I have some code which produces the following outputs:

density = 456
pressure = 356 
temperature = 66

How can I store these variables and their names in an array to save them from being printed in the terminal for example?

Answer 1

[Chunru]

density = 456;
pressure = 356 ;
temperature = 66;

% or use struct
a.density = 456;
a.pressure = 356 ;
a.temperature = 66;

use 'who' to list variables in workspace?
