Help me with this code.

function k = SPK1(w1,v,m,n)

w=transpose(w1);
for i1= 1:n 
p1=0;
q1=0;
r2=0;
 
for j1=1:m
% summation of upper numerator portion  
    p1= p1+ w(i1,j1)* v(j1);  
end

for i2=1:n
for j2=1:m
% upper denumerator poriton 
 q1=q1+w(i2,j2);
end 
end
%the upper portion of equation 
r1 = p1/q1;

for i3= 1: n
p2=0;
q2=0;
for j3=1: m
% summation of lower numerator portion 
    p2= p2+ w(i3,j3)* v(j3);  
end

for i4=1:n
for j4=1:m
% lower denumerator poriton 
 q2=q2+w(i4,j4);
end 
end
%the lower portion of equation

r2 = r2+ p2/q2;

end
%the final value 
k(i1)=r1/r2;
end 
end

Is the coding correct and logical for this equation? if not, kindly suggest me.

thanks.

I don't immediately notice anything strange (although I didn't check in detail).

Why aren't using the sum function? That would make it easier to read and probably a bit faster.

How can i use the sum function for my problems? Can you share a bit more?

[Rik]

would become

sum(w(1:n,j))

Note that for element-wise multiplication and division you need .* and ./.

Thanks.

How to write the Wij when no sum?

Where, i=4, j=10

Like this, w(1:4,10) ?

[Rik]

Just normal indexing:

i=4;j=10;
w(i,j)
