How can I open an empty external text file and fill it with the concatenation of two vectors and a char inbetween

I have two vectors

one is:

a=[1.4;3.1;6.5]

and the other one is:

b={VAR1,VAR2,VAR3}

How can I open an empty external text file, named a2.txt and fill the 3 first lines with

VAR1=1.4

VAR2=3.1

VAR3=6.5

I thank you in advance

Best regards,

Try this:

fid = fopen('a2.txt', 'wt');
fprintf(fid, '%s=%.1f\n', b{1}, a(1));
fprintf(fid, '%s=%.1f\n', b{2}, a(2));
fprintf(fid, '%s=%.1f\n', b{3}, a(3));
fclose(fid);
