hi,

for the derivation

enenrgy= summation of ( modulus of d(i)(j))^2 ) i= 1........L and j=1.......N which one would be correct in matlab?


set 1:

energy1=0
for i=i:N-1
for j=1:L-1
temp1=d(i)
temp2=d(j)
temp3=temp1 * temp2;
energy1=energy1+ (temp3*temp3)
end
end

note: this program would provide the energy for each coefficients values, am i right?

set 2:

double d[L][N]
double enenrgy=0
for i=i:N-1
for j=1:L-1
enenrgy+=d[i][j]^2
end
end

set 3:

double energy=0
for i=i:N-1
for j=1:L-1
enenrgy=(i%j)*(i%j);
energy+=energy;
end
end



pls sir. tell me which one would provide the better result? which get suit for above derivation in matlab.
