I want to disply the output of my variable. so i created the following code.
food= { 'Rice','Quinoa','Tortilla','Lentils','Broccoli' }';
X % X is the output
for n =1:length(X)
disp(food{X(ii)})
end
The code is not working. Any help will be appreciated.

Access the contents of cells by indexing with curly braces, {}.
food= { 'Rice','Quinoa','Tortilla','Lentils','Broccoli' }';
for n =1:length(food)
disp(food{n})
end

Please clear all the pre defined variables before running the code.
Index cannot be float. It must be an integer.
Below is the working complete code.
clc
clear
food= { 'Rice','Quinoa','Tortilla','Lentils','Broccoli' }
X=[2,5]
for n =1:length(X)
disp(food{X(n)})
end

Thanks for the feedback. The code did work. However this is not the outcome I wanted.
I wanted to display, values of my X variable. X values are output from my optimization function.
Each index of my X(i) corresponds to same index in the food array.
Displaying only the values of X(i), one will not know the food associated with it. That is why i want to display the string i.e. food. associated with the value of X.
