error in performing summation

I have an equation

summation i= 1 to n,Q^2ir/(Mi+M+r)

where

n=99

S=2

qir is the number of samples with class i (i = 1,2,. . . ,S, and r = 1,2,. . . ,n) in the interval (dr-1,d),Mi+ is the total number of samples with class i, and M+r is the total number of samples in the interval (dr-1,d)

Mi+=60

wen i calculate i get only one value,but the outout must be of many values..please help

[TAB]

Please post your code, so that we can suggest what is going wrong.

[kash]

for i=1:2

for r=1:99

Z=ceil(sum(q(i,r).^2)

end

end

[kash]

if my code is wrong can u please code for me

I am guessing that if x is your answer that you want to have many values that you are doing something like

x = calc(a,b,c,i)

instead of

x(i) = calc(a,b,c,i)

also don't forget to preallocate x.

EDIT based on your comment to the question:

Z(i,r) = ceil( ...

you also probably want to add:

Z = zeros(2, 99);

before the loops.

[kash]

for i=1:2

for r=1:99

Z=ceil(sum(q(i,r).^2)

end

end

this is the code

Daniel can u say what is (a,b,c)

if my code is wrong can u please code for me
