i need to calculate fitness value and save that in separate .mat file

n=number of node (i have 100 nodes)

mch = cluster head per each round of node (here i gave number of round =30 nd i get 14 cluster head nodes) % didnt take repeted cluster heads

residual energy = sum of energy for 30 rounds

p1 and p2= randam numbers between 0 abd 1

i store mch in mat nd residualenergy into another mat file

i need to calculate each time fitness value for 100 nodes based on my cluster heads and residual energy

for i=1:n

Fit = p1 .*(n.* (mch(i,:))) + p2 .*sum (resdialenergy(i,:))

end

error at

Index in position 1 exceeds array bounds.

Error in ch_rnd (line 305)

Fit = p1 .*(n.* (mch(i,:))) + p2 .*sum (resdialenergy(i,:))

i need to sort this kindly help me its urgent
