MatLab Loop To Display Information From A Vector and a String Array

So I have a string array with the names of 5 history textbooks, and a list below containing their consecutive prices in dollars. I want to create a loop function that sorts the prices and lists the names of the textbooks as well. I know how to create a loop that sorts the prices, but I don't know how to make the function list the textbook each price belongs to. Any help would be greatly appreciated. Thanks 

%LIST OF TEXTBOOKS

TB = ["1. America Past and Present - Divine","2. America's History - Henretta","3. Unfinished Nation - Brinkley","4. Out of Many - Faragher","5.The American Pageant - Kennedy"];

%LIST CONTAINING TEXTBOOK PRICES IN DOLLARS 

cost = [118 120 97 102 89]; 

%HERE I WANT TO WRITE A FUNCTION THAT RETURNS THE TEXTBOOK NAME AND IT'S PRICE

If you want to stick with your loop code, you can append to an initially empty new list the TB(x), (after you find the min inside the loop) , and finally overrun TB by that list, as you do for 'cost'.

Alternatively, you can for example use MATLAB's sort() function, retrieve its indices and apply them on TB, like:

[~, I] = sort(cost) ;
TB = TB(I) ;

Also, if you plan to use the book-cost structure a lot, you can define them as a table and then you can use MATLAB's sortrows() function, that can be applied to tables. See the doc, in particular - the sorting by table's variables.
