Getting the value of variable from its name

I have variable name saved as a string in an array. I want to read the value of the variable into another array. Is there a function in matla which takes variable name as input and returns the value of that variable.

eval will do this, but see the link posted by Stephen explaining all the reasons you should avoid using eval: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval

For example:

a = 1:10;
varName = 'a';
b = eval(varName);

Correction: "see the link by Stephen which explains the main reasons why you should avoid forcing meta-data (e.g. pseudo-indices, test parameter values, etc.) into variable names or fieldnames."
