Hey guys,
I work with matrix that have words on one column and their corresponding value on the other column as such
'Apple' 13.6000000000000
'Apple' 7.23200000000000
'Apple' 6.73600000000000
'Ball' 1.34900000000000
'Cat' 1.71600000000000
'Dog' 2.66100000000000
'Cat' 0.771000000000000
and the order of these words is random. I need to calculate the mean for individual words. I appretiate any help.
thanks

T = readtable('txtfile.txt')
T_out = varfun(@mean,T,'GroupingVariables','Var1');

[unique_names, ~, idx] = unique(YourCell(:,1));
mean_per_word = accumarray(idx, cell2mat(YourCell(:,2)), [], @mean);
output = [unique_names, num2cell(mean_per_word)];
