extract out values out of loop

Can any one pls help how to extarct [XYZ,H,D,I,F] out of the below loop

Thanks

for i= 1: length(Hi)

[XYZ,H,D,I,F] = wrldmagm(Hi(i),Lat(i),Long(i),decimalYear(i));

end

Can

Preallocate and index, maybe?

Make them arrays and assign to the elements. E.g.,

for i= 1: length(Hi)
    [XYZ(:,i),H(i),D(i),I(i),F(i)] = wrldmagm(Hi(i),Lat(i),Long(i),decimalYear(i));
end

Consider pre-allocating XYZ, H, D, I, and F also.

% Pre-allocation of the output:
len = length(Hi);
XYZ = zeros(3, len);
H   = zeros(1, len);
D   = zeros(1, len);
I   = zeros(1, len);
F   = zeros(1, len);

for i = 1:length(Hi)
  [XYZ(:, i), H(i), D(i), I(i), F(i)] = wrldmagm(Hi(i), Lat(i), Long(i), decimalYear(i));
end
