If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
TUTORIAL: How to ask a question (on Answers) and get a fast answer
To save the variable to a .mat file:
save('answers.mat', 'TABELA_P1_PES');

A thousand pardons for the delay, I was at university until the moment... well, here is attached my table of values. I spent all afternoon trying to get the values ​​and calculate the percentage of appearance in each of the columns, but so far I have not been successful.

There is a function named “tabulate” that displays the frequency table of the data in the vector x.If we do conversion of table to vector, we can use this function directly. Checkout the below link for more information:

It would be nice if the tabulate function works, but I need the percentage of the letters that are not showing and tabulate do not show those numbers.
