MATLAB: Substitute syms in 2D array to have 3D array

Question

I have a 2D array of syms and I want to substitute the syms variables with 1D array. How do i do it? If a form a loop it takes a long runtime.

sample code:

syms a b c
arr=[0 0 0;0 0 0;a b c];
a=[1 2 3 4 5]';
b=[2 3 4 5 6]';
c=[5 6 7 8 9]';
subs(arr)

The output should be a 3x3x5 matrix. Please help

I have the following code using loops:

    syms a b c
arr=[0 0 0;0 0 0;a b c];
J=zeros(3,3,5);
a1=[1 2 3 4 5]';
  b1=[2 3 4 5 6]';
  c1=[5 6 7 8 9]';
for i=1:5
a=a1(i);
b=b1(i);
c=c1(i);
J(i)=subs(arr);
end

Answer 1

subs() is not able to do this for you, as you need to replicate the other elements of the array. I do not think you will be able to do this without a loop (though you can probably hide the loop using arrayfun())
