function to read a cell contents

Hello everybody! As the example shows, i would like that the genre of the variable will be recognized and declared (with print at the screen) and then divided creating two different matrices.Does anybody know the function that i need?

data = {'tomato','VEGETABLE';'banana','FRUIT';'grapes','FRUIT';'pepper','VEGETABLE';'carrot','VEGETABLE';'pear','FRUIT'}
class1 = 'FRUIT'
class2 = 'VEGETABLE'
data1 = {'tomato','VEGETABLE';'pepper','VEGETABLE';'carrot','VEGETABLE'}
data2 = {'banana','FRUIT';'grapes','FRUIT';'pear','FRUIT'}

What is the purpose? Splitting arrays is not usually recommended if you need to scale up.

my purpose is select from the input database only the values that i'm interesting in thanks to the "kind's" recognizement (of course the type is unknown)

I discourage creating incrementally numbered variables in the workspace, however here's the bare-bone approach:

% Index vegetables
idx = strcmpi(data(:,2),'vegetable');

% Select vegetable entries
data(idx,1)

Now, you can automate and throw everything into a, e.g. structure:

% Throw everything into a structure 
[unData, ~, idxData] = unique(data(:,2));

for n = 1:numel(unData)
    s.(unData{n}) = data(idxData == n,1);
end

s.FRUIT
s.VEGETABLE
