Running for loops in parallel

I have 3 variants each with a different number of options and want to score these. So at the moment I have a code which looks as follows:

for n = 1:numel(variant1)
    [y1_v1,y2_v1]=calcscoreV1(x1_v1,x2_v1)
end
for n = 1:numel(variant2)
    [y1_v2,y2_v2]=calcscoreV2(x1_v2,x2_v2)
end
for n = 1:numel(variant3)
    [y1_v3,y2_v3]=calcscoreV3(x1_v3,x2_v3)
end

As these three for loops and their respective functions used are independent of each other, I was wondering if it is perhaps possible to run all 3 loops simultaneously to save computational time?

Thanks in advance.

parfor k = 1:3
  if k == 1
    for n = 1:numel(variant1)
      [y1_v1,y2_v1]=calcscoreV1(x1_v1,x2_v1)
    end
  elseif k == 2
    for n = 1:numel(variant2)
      [y1_v2,y2_v2]=calcscoreV2(x1_v2,x2_v2)
    end
  else  % k == 3 and default:
    for n = 1:numel(variant3)
      [y1_v3,y2_v3]=calcscoreV3(x1_v3,x2_v3)
    end
  end
end

Of course the outputs y1_v1 etc. must be store in a meaningful way.
