The main purpose of this paper is to obtain the unique solution of the constant coefficient homogeneous linear fractional differential equations 𝐷𝑞𝑡0𝑋(𝑡)=𝑃𝑋(𝑡),𝑋(𝑎)=𝐵 and the constant coefficient nonhomogeneous linear fractional differential equations 𝐷𝑞𝑡0𝑋(𝑡)=𝑃𝑋(𝑡)+𝐷,𝑋(𝑎)=𝐵 if 𝑃 is a diagonal matrix and 𝑋(𝑡)𝐶1𝑞[𝑡0,𝑇]×𝐶1𝑞[𝑡0,𝑇]××𝐶1𝑞[𝑡0,𝑇] and prove the existence and uniqueness of these two kinds of equations for any 𝑃𝐿(𝑅𝑚) and 𝑋(𝑡)𝐶1𝑞[𝑡0,𝑇]×𝐶1𝑞[𝑡0,𝑇]××𝐶1𝑞[𝑡0,𝑇]. Then we give two examples to demonstrate the main results.
