Hi Bill
You could use
a[t_]=Table[c[i, t],{i,n}] (1)
or, with subscripts:
\!\(a[t_] = Table[c\_i[t], {i, n}]\) (2)
(you can then avoid the c's and use a for the components as well:
\!\(a[t_] = Table[a\_i[t], {i, n}]\) (3)
)
Then you would define f[x_] this way:
f[x_,t_]:= Sum[a[t][[k]] p[k, x], {k, n}] (all cases)
or
\!\(f[x_, t_] := \ Sum[c\_k[t]\ p[k, \ x], \ {k, \ n}]\) (case 2)
or
\!\(f[x_, t_] := \ Sum[a\_k[t]\ p[k, \ x], \ {k, \ n}]\) (case 3)
(Paste all these expression into your Notebook. Then they will be
formatted by the front end.)
Yours sincerely
Bruno
