“…Furthermore, in Figure , the logarithmic graphs of MAEs ( l o g 10 E r r o r ) is displayed using the present algorithm at θ = ϑ =− 0.5 for α = 0.1,0.3,0.5,0.7,0.9 with various values of N ( N = M ). Clearly, the numerical errors decay exponentially as N increases.Example Consider the following linear inhomogeneous time‐fractional equation : subject to the boundary conditions and the initial condition u ( x ,0) = x 2 . The exact solution of this problem is …”
