Create an array containing numeric and symbolic variables

I am trying to create an array that contains both numeric and symbolic variables. I need both as certain values will be tested if they are symbolic or not using isnumeric(); however, when trying to test these values they all come back as symbolic, is there a way around this? Code below:

syms t1 t2 d;

DH = [0 0.4   0 t1  %i = 1
      0 0.1 -90 t2  %i = 2
      0 d  90 0]; %i = 3

Thanks!

syms t1 t2 d;
DH = {0 0.4   0 t1  %i = 1
      0 0.1 -90 t2  %i = 2
      0 d  90 0} %i = 3

DH = 3×4 cell array
    {[0]}    {[0.4000]}    {[  0]}    {[t1]}
    {[0]}    {[0.1000]}    {[-90]}    {[t2]}
    {[0]}    {[d     ]}    {[ 90]}    {[ 0]}

isnumeric(DH{1,1})

ans = logical
   1

isnumeric(DH{1,4})

ans = logical
   0
