What is a "direct MATLAB command"? Even
3 + 5
is considered a command and invokes a MATLAB function ("plus")

pix_1 = [p11,p12];
pix_2 = [p21,p22];
distance = sqrt( (p21-p11)^2 + (p22-p12)^2 );

bwdist() does not compute distance between millions of points. bwdist() finds the points that are not part of objects, and calculates the distance from each point to the closest point that is part of some object.
If you want to operate on multiple points, then the small change to the formula already given is
distance = sqrt( (p21-p11).^2 + (p22-p12).^2 );
where the variables given there are all vectors.
If you want to calculate the distance of each point to every other point then you can use pdist() from the Stats toolbox.

if you have two vectors with any number of point, for instance, x1=[1 2 3 4 5] and x2=[2 3 4 5 6], then Euc_dist = norm( x1 - x2 ) ;
