Hello Friends,
I need to solve this " F=(cos(q1)+cos(q2))*i '', where summation is over i from 1 to 100 and q1 and q2 are square matrices. Please help me out to solve this. I will be highly grateful.

This equation can be solved without any loops, but as you asked this code meets your requirement:
q1 = [1 2 3; 4 5 6; 7 8 9 ];
q2 = [10 11 12; 13 14 15; 7 8 9 ];
S = cos(q1)+cos(q2);
F = 0;
for i = 1:100
F = F+S*i;
end

#Without Loop Recomended
syms i
F_result=symsum((cos(q1)+cos(q2))*i,i,1,100)
