Output numeric array from symbolic evaluation

Question

0 个投票

I am trying to evaluate some symbolic functions at specific datapoints using nested loops and output the results to an array.

While the results in the output window are the numeric values, the array contents are not.

How can I correct this to get the numeric results in the array?

syms d1 d2 d3 ma mb x0 u3 u4;
ma = (d2-d1);
mb = (d3-d2);
x0 = ma*mb;
u3 = diff(x0,d3)
u4 = diff(x0,d2)
T = [];
next = 1;next1 = 1;next2=1;
for next2 = 1:35:5;
    for next = 1:4;
      %example values
      b1 = 1*next/2; 
         b3 = b1+2; 
          for next1 = [0.05,0.1,0.4,0.65,0.9];
          b2 = b1*next1;  
          z=vpa(subs(u3,{d1,d2,d3},{b1,b2,b3}),4)
          g=vpa(subs(u4,{d1,d2,d3},{b1,b2,b3}),4)
          T = [T;b1,b2,b3,z,g];
          end
    end
end
