Hi Preet,

You can use map() function to store previous indices of elements in array and then sort the arrray.

You can refer Sort vector using loops - MATLAB Answers - MATLAB Central (mathworks.com) for sorting a vector without using builtin functions i.e. by using loops.

Refer to the below documentation for more information:

Create Map Object - MATLAB & Simulink (mathworks.com)

Hope it helps.
