function to read a cell contents

2 views (last 30 days)
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.

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
