for t=1:6
f=((t-1)/10);
C(x,t)=series(e,f);
end
end
The following error occurred converting from sym to double:
Unable to convert expression into double array.
Error in fractionakelingordanequation (line 33)
C(x,t)=series(e,f);

it looks like this particular function is undefined at (0,0), so you might have some issues with that loop

Preallocate C to be a sym array.
syms x
C=zeros(3, 6, 'sym')
C = 
C(2, 3) = x.^2
C =
