how do i bold certain characters in a vector?

I am trying to bold an i,j, and k for vector equations. How can I do this using fprintf?

p=[-1,7,-3]; v=[5,12,-7];
syms t
vec=p+t*v
fprintf('The vector equation for the line is %si+%sj+%sk\n and the parametric equations are x= %s,\ny= %s, z=%s',vec,vec)

thanks!

You can try Element Style tag:

fprintf(['The vector equation for the line is %s', ...
['<strong>i</strong>'], ...
'+%s', ...
['<strong>j</strong>'], ...
'+%s', ...
['<strong>k</strong>'], ...
'\n and the parametric equations are x= %s,\ny= %s, z=%s\n'],vec,vec)

This can bolden the three characters: i, j, k

Oh, this does work! Nice - didn't realize there was this feature.
