Suppose I have a forloop that yields a 1x3 output
for i = [1:3]
mdl = fitlm(X((30*i-30+1):i*30,:),Y((30*i-30+1):i*30,3))
montherrors(:,i) = mdl.Residuals(:,1)
errors = table2array(montherrors)
stdev = std(errors, 1)
idio_three = stdev * sqrt(ndays)
end
And another loop that also yields a 1x3 output
i = 1
for j = [1:3]
mdl = fitlm(X((30*i-30+1):i*30,:),Y((30*i-30+1):i*30,j))
montherrors(:,j) = mdl.Residuals(:,1)
errors = table2array(montherrors)
stdev = std(errors, 1)
idio_j = stdev * sqrt(ndays)
end
Now I would like to combine the two to obtain a 3x3 matrix output. I have tried multiple strategies but cant seem to figure it out.
I tried
for j = [1:3]
for i = [1:3]
mdl = fitlm(X((30*i-30+1):i*30,:),Y((30*i-30+1):i*30,j))
montherrors(:,(i*j)) = mdl.Residuals(:,1)
errors = table2array(montherrors)
stdev = std(errors, 1)
idio_one(j,:) = stdev * sqrt(ndays)
end
end
But then i get the error Cannot create a table variable with a discontiguous index.
