Calculating percent of data in table

I have a 1x12 table, Is there any quick way or function to find percentage for each column based on total?

for example:

data = (1,2,3)

percent first = (1*100)/(1+2+3) = 16.66 %

percent two = (2*100)/(1+2+3) = 33.33 %

"I have a 1x12 table,"

So you have a table with 1 column? The rest of your question sounds like you have >1 column.

I'm sorry you right; I have a table like this:

For the following table:

T = table;
T.data = randi(10,1,12);

you can use:

T.percentages = 100 * T.data ./ sum(T.data);

which gives:

>> T.data

ans =

    10     1     9     2     5     3     2     3     9    10     4     9

>> T.percentages

ans =

   14.9254    1.4925   13.4328    2.9851    7.4627    4.4776    2.9851    4.4776   13.4328   14.9254    5.9701   13.4328

and to be sure:

>> sum(T.percentages)

ans =

   100

Thank you, It workes great. I forgot to attach a sample, Did you know-how about when I have such a data set?

I tried to change the code to works, but always I got an error

'operator '*' is not supported for operands of type 'table'

Thanks again

For that table, you could use { } indexing to obtain the cells within and then cell2mat to convert to a double array:

arr = cell2mat(data{1,:});
percentages = 100 * arr ./ sum(arr);
