Matlab c/c++ question

Question

As you see in the code the last part is repeated as 70,0,0
How to substitute all these following variables without writing each time as 70,0,0
d2=simplify(subs(d2,{b2u, b2v, b2w, a2x, a2y, a2z, L2, alf, bet, gam},{30,18,0,70,-41,-100,105,70,0,0}))

c3z=B3_A(3,1)-sqrt(L3^2-(B3_A(1,1)-a3x)^2-(B3_A(2,1)-a3y)^2);
d3=c3z-a3z
d3=simplify(subs(d3,{b3u, b3v, b3w, a3x, a3y, a3z, L3, alf, bet, gam},{-30,18,0,0,81,-100,105,70,0,0}))
d3=double(d3)
d2=double(d2)
c1z=B1_A(3,1)-sqrt(L1^2-(B1_A(1,1)-a1x)^2-(B1_A(2,1)-a1y)^2);
d1=c1z-a1z
d1=simplify(subs(d1,{b1u, b1v, b1w, a1x, a1y, a1z, L1, alf, bet, gam},{0,-35,0,-70,-41,-100,105,70,0,0}))
d1=double(d1)
c1z=simplify(subs(c1z,{b1u, b1v, b1w, a1x, a1y, a1z, L1, alf, bet, gam},{0,-35,0,-70,-41,-100,105,70,0,0}))
c1z=double(c1z)
c2z=simplify(subs(c2z,{b2u, b2v, b2w, a2x, a2y, a2z, L2, alf, bet, gam},{30,18,0,70,-41,-100,105,70,0,0}))
c2z=double(c2z)
c3z=simplify(subs(c3z,{b3u, b3v, b3w, a3x, a3y, a3z, L3, alf, bet, gam},{-30,18,0,0,81,-100,105,70,0,0}))
c3z=double(c3z)
R_AB=simplify(subs(R_AB,{b3u, b3v, b3w, a3x, a3y, a3z, L3, alf, bet, gam},{-30,18,0,0,81,-100,105,70,0,0}))
B3_A=simplify(subs(B3_A,{b3u, b3v, b3w, a3x, a3y, a3z, L3, alf, bet, gam},{-30,18,0,0,81,-100,105,70,0,0}))
B2_A=simplify(subs(B2_A,{b2u, b2v, b2w, a2x, a2y, a2z, L2, alf, bet, gam},{30,18,0,70,-41,-100,105,70,0,0}))
B1_A=simplify(subs(B1_A,{b1u, b1v, b1w, a1x, a1y, a1z, L1, alf, bet, gam},{0,-35,0,-70,-41,-100,105,70,0,0}))

Answer 1

% define constant cell
A={30,18,0,70,-41,-100,105,70,0,0};
%%
d2=simplify(subs(d2,{b2u, b2v, b2w, a2x, a2y, a2z, L2, alf, bet, gam},A));
