a=1:5;
b=90:94;
fprintf('Variables A : %.f | Variables B : %.f\n',a,b);
Consider the script above.
Variable a are the small values. I want to print all the variables on the LEFT COLUMN. Then variable b on the RIGHT column.
However with this sequence of fprintf the variable a results in an entirely different order.
1 2
3 4
5 90
91 92
93 94

The trick is [a;b], like this
fprintf('Variables A : %.f | Variables B : %.f\n',[a;b]);

fprintf(fileID,formatSpec,A1,...,An) applies the formatSpec to all elements of arrays A1,...An in column order, and writes the data to a text file.
If you have R2016b or later you might also want to look at compose(), which does not have this same behaviour.

The fundamental point is that Matlab arrays are column-based. We might read row by row when we look at an array to be written, but Matlab doesn't. Maybe there should be a warning to this effect in the doc, but as far as I'm aware there isn't. If you want to avoid ambiguous situations, you should provide each input as a separate array.
