Calculate normals from nodes which form a 3D curve

I have a composed cell:
in the first column: the P nodes;
in the second column: the circular geometries
in the third through fifth columns: the components a,b,c of the normal N of the circular geometry
Having other P nodes (see matrix ‘coord’) how can I calculate, for those nodes, the new components of the normal (a,b,c)?
load(‘test_p.mat’)

figure(‘units’,’normalized’,’outerposition’,[0 0 1 1]);
plot3(coord(:,1),coord(:,2),coord(:,3),’k.’,’Markersize’,5);
hold on
for t = 1:height(circle)
plot3(circle{t,1}(:,1),circle{t,1}(:,2),circle{t,1}(:,3),’k.’,’Markersize’,20);
patch(circle{t,2}(:,1),circle{t,2}(:,2),circle{t,2}(:,3),’k’,’FaceAlpha’,0.5);
end
hold off
