Create an array containing numeric and symbolic variables

4 views (last 30 days)
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
