HI everyone
I have a loop and anticipate to get a sym or equation at the end but I am having a matrix. My question is how can I convert this matrix to symbols so that I can easily evaluate it.
X = [-0.8078;-0.0003;0.0002;1.0035];
x = [x1;x2;x3;x4];
[m,n]=size(x);
for i=1:n-1
aa = x(i).^vpa(X(i+1,1))
end
This is the result.
aa =[1/x1^3.568e-5, x2^7.104e^-6,x3^1.003]
But I would loved it this way
aa =[1/x1^3.568e-5 * x2^7.104e^-6*x3^1.003]

You are overwriting all of aa each time through the loop.
Perhaps you should initialize
aa = sym(1);
and then in the loop,
aa = aa * x(i).^vpa(X(i+1,1));
