how to divide a matrix by its norm in for loop

i want s/|s|

s=[x(2)+x(1);x(1)+x(3)];

i write as it

for i=1:n

s1(i)=x2(i)+x1(i);

s2(i)=x1(i)+x3(i);

sm(:,i)=[s1(i);s2(i)];

if ( x(i)~=0 )

u1(i)=s2(i)/norm(sm(:,i));

u2(i)=-0.1*s1(i)/norm(sm(:,i));

end

end

pleae help me

There's no need for a for loop here. Just use the norm function and divide. If you were trying to divide each row or each column of the matrix by its vector norm instead of dividing the whole matrix by its matrix norm, use the vecnorm function instead.

but i want plot it so i am using for loop and x1 x2 x3 are state that i obtain from ode45
