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);
