add each iteration of for loop to a table

11 views (last 30 days)
Hi,
I have the following code;
f=dir('*.csv');
for i=1:length(f)
x=readtable(f(i).name)
y=[sum(x.LogicRate100),sum(x.LogicRate125),sum(x.LogicRate150),sum(x.LogicRate170),sum(x.LogicPower50),sum(x.LogicPower66),sum(x.LogicPower75),sum(x.LogicPower80)]
y=array2table(y)
writetable(y,['out' num2str(i) '.csv']);
end
It reads each file in the and sums the 8 collumns to produce a vairale (y).
I want the output to be a table or array that each row contains the output of each iteration. Currently, I am just saving each row.

f=dir('*.csv');
T = zeros(length(f),[]) ;
for i=1:length(f)
x=readtable(f(i).name)
y=[sum(x.LogicRate100),sum(x.LogicRate125),sum(x.LogicRate150),sum(x.LogicRate170),sum(x.LogicPower50),sum(x.LogicPower66),sum(x.LogicPower75),sum(x.LogicPower80)]
y=array2table(y)
T(i,:) = table2array(y) ;
end
writematrix(T,'test.csv')

Do you suggest just to use an array in the sum line?
