Want to use a vector as parameter to a function, without having to separate its elements

Question

If I call a matlab function with: func(1,2,3,4,5) it works perfectly.

But if I do: a=[1,2,3,4,5] %(a[1;2;3;4;5

Answer 1

Use eval:

astr = [];
for i=1:length(a)
    astr     = [astr,'a(',num2str(i),'),']; % a(1),a(2),...
end
astr  = astr(1:end-1);
eval(['func(' astr ');']);
