How to add a whole field at once (if possible)?

Here is a shortened version of the code:

 %stars in the Orion constellation
etoile(1).nom='Betelgeuse';
etoile(1).dist_al=490;
etoile(1).magnitude=0.44;
etoile(2).nom='Bellatrix';
etoile(2).dist_al=250;
etoile(2).magnitude=1.64;
etoile(3)=struct('nom','Saiph','dist_al',650,'magnitude',2.06);
%Add a field (luminosity compared to the sun)
etoile(1).luminosite_nxsoleil=120000;
etoile(2).luminosite_nxsoleil=10000;
etoile(3).luminosite_nxsoleil=50000;

Is there any way to do the last three lines (creating a new field containing 12000 10000 and 50000) in one operation?

Thanks!

Answer 1

[Walter Roberson]

lums = [12000 10000 50000];

%I will presume that the luminosities are being read in somehow, rather than
%being hard coded.

lumsc = num2cell(lums);
[etoile.luminosite_nxsoleil] = deal(lumsc{:});

If you were hard coding then

lums = {12000 10000 50000};
[etoile.luminosite_nxsoleil] = deal(lums{:});

 [etoile(1:3).luminosite_nxsoleil] = deal(120000,10000,50000)

Thanks! The deal function is exactly what I was looking for!
