Consider the following
a = 3; b=7; c=5; d=9;
save('test.mat')
data = load('test.mat');
toSave = { 'b' ; 'c' };
writecell( horzcat( toSave , <missing code> ) ,'myfile.csv')
what should be the <missing code> in order to have the content of myfile.csv to be
b , 7
c , 5
?

This should do the trick. If the variables aren't scalars the results might not be what you want.
a = 3; b=7; c=5; d=9;
save('test.mat')
data = load('test.mat');
toSave = { 'b' ; 'c' };
s=struct;
for n=1:numel(toSave)
s.(toSave{n})=data.(toSave{n});
end
writecell( horzcat( toSave , struct2cell(s) ) ,'myfile.csv')

I totally forgot the simple way of selective loading.
Thanks for the hint.

Thanks to the inspiring answer of @Rik, I found the following solution without the need to use for loop
a = 3; b=7; c=5; d=9;
save('test.mat')
data = load('test.mat');
toSave = { 'b' ; 'c' };
writecell(horzcat(toSave, cellfun( @(C) data.(C),toSave,'UniformOutput',false)),'myfile.csv')

You are right, but I can't resist minimizing the code despite knowing it is not the best practice :)
