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')
