One equation, two unknowns, K1 and K2 fall on a line for each i, infinite solutions for each i.

Answer 1

[Yongjian Feng]

If I and V are vectors, you can just call solve to do the job:

I = [1 2];
V = [3 4];
syms K1
syms K2
eq = I == (K1.*V+(K2.*V.^0.5));
sol = solve(eq)
sol.K1
sol.K2

Answer 2

[David Hill]

I=[1 2];
V=[3 4];
K=[V',sqrt(V)']\I';
