Is it possible to generate a plan of limited dimensions, for example a 10x10 square?
line = importdata("line_w.mat");
normal = importdata("normal_w.mat");
row = 10; % variabile
P = line(row,:);
plane = normal(row,:);
a=plane(1); b=plane(2); c=plane(3);
d=dot(plane,P);
figure
plot3(line(:,1),line(:,2),line(:,3),'r.','Markersize',10);
hold on
plot3(P(:,1),P(:,2),P(:,3),'b.','Markersize',15);
fimplicit3(@(x,y,z) a*x+b*y+z*c-d)
hold off
axis equal
xlabel('x')
ylabel('y')
zlabel('z')
xlim([0 50])
ylim([-50 20])

You can use patch.
[a,b,c]=deal(1); %fake input data
P=[1 1 1];
R=2;
t=(0:359)';
V=R*[cosd(t),sind(t)]*null([a,b,c])' + P(:)';
patch(V(:,1), V(:,2),V(:,3),'r'); axis square
view(40,25); grid on

Perhaps try rescaling the appropriate variables with rescale.

Thanks for the response. Could you tell me how to obtain the matrix to use in 'rescale'?
Also, is it possible to generate, on that plane created with fimplicit3, a circular-shaped plane defined by the radius R?
