L1=1;L2=2; L3=3; D1=2;D2=3; D3=5;
Then how will i do
C=(L1*D1)+(L2*D2)+(L3*D3)
in MATLAB using programming (similarly i have to do 350 number of L and D). Kindly help me out.
i was trying like this one;
sum=0
for i=1:3
C=Li*Di
end
but couldn't succeed. kindly help

"similarly i have to do 350 number of L and D"
Then you should put your data into matrices, and so make your task trival. The name MATLAB comes from "MATrix LABoratory", and not from "lets put data into lots of separate numbered variables and make our code slow and complex".

I would create vectors out of the ‘L’ and ‘D’ values, then multiply them using vector/matrix multiplication:
L1=1; L2=2; L3=3; D1=2; D2=3; D3=5;
L = [L1 L2 L3];
D = [D1 D2 D3];
C = L * D';
Note the transpose operator (') for ‘D’. That is necessary to produce the result you want.
