Avoid multiple output using fprintf of multiple variables in livescript

My script is:

k=[3.96306869127352e-05;
   1.33047441644794e-05;
   3.37761112449900e-05;
   7.19380417629400e-06];

confk=[2.95622613104490e-05;
       6.38219462217362e-06;
       1.15227436682386e-05;
       8.98428923906260e-05];

formatSpec = 'k1=%4.2e +/- %8.3e;\n';
f1=fprintf(formatSpec,k(1),confk(1));

k1=3.96e-05 +/- 2.956e-05;

formatSpec = 'k2=%4.2e +/- %8.3e;\n';
fprintf(formatSpec,k(2),confk(2));

k2=1.33e-05 +/- 6.382e-06;

formatSpec = 'k3=%4.2e +/- %8.3e;\n';
fprintf(formatSpec,k(3),confk(3));

k3=3.38e-05 +/- 1.152e-05;

formatSpec = 'k4=%4.2e +/- %8.3e;\n';
fprintf(formatSpec,k(4),confk(4));

k4=7.19e-06 +/- 8.984e-05;

Even if it works that way, what I want is that it comes out one output and not one for each. I tried this way:

formatSpec='k=%4.2e +/- %8.3e\n';
fprintf(formatSpec,k,confk)

k=3.96e-05 +/- 1.330e-05
k=3.38e-05 +/- 7.194e-06
k=2.96e-05 +/- 6.382e-06
k=1.15e-05 +/- 8.984e-05

But so they don’t come out "k1,k2,k3,k4". I also tried with a for cycle but nothing done.

k=[3.96306869127352e-05;
   1.33047441644794e-05;
   3.37761112449900e-05;
   7.19380417629400e-06];

confk=[2.95622613104490e-05;
       6.38219462217362e-06;
       1.15227436682386e-05;
       8.98428923906260e-05];

formatSpec='k%d=%4.2e +/- %8.3e\n';

fprintf(formatSpec,[(1:numel(k))' k confk]')

k1=3.96e-05 +/- 2.956e-05
k2=1.33e-05 +/- 6.382e-06
k3=3.38e-05 +/- 1.152e-05
k4=7.19e-06 +/- 8.984e-05
