Call the data in string

Let say I have a set of matrices

apple=[1 0 0
       1 0 1];
orange=[1 0 0 1
       1 1 1 0];
guava=[1 1 0 1
       1 0 1 0];

Then I save it in a vector name fruit

   fruit={'apple','orange','guava'}

Let say I want the matrix for orange, how can I do it?

[Walter Roberson]

fruit_vals = {apple, orange, guava};

to_find = 'orange';
[tf, idx] = ismember(tolower(to_find), tolower(fruit));
if ~tf
    fprintf('"%s" is not a known fruit\n', to_find);
    associated_val = [];
else
    associated_val = fruit_vals{idx};
end

fruit.apple=[1 0 0
       1 0 1];
fruit.orange=[1 0 0 1
       1 1 1 0];
fruit.guava=[1 1 0 1
       1 0 1 0];
   
fruit.('orange')
