Empty sym: 0-by-1 Error

I am trying to find an interative solution to a problem I have. My TA in the class gave me this script and his works perfectly; however, mine gives me an Empty sym: 0-by-1 error whenever I try to run it.

Here is my script:

Data = [5.542803392, 2.874974422, 0.116610421, 1.897079378;

88.51537734, 3.18981575, 0.3460802, 22.83417623];

[row,col]=size(Data);

for n=1:row

syms t

Age_638 = Age638(1/Data(n,1))/1e+6;

R = Data(n,3);

Age7_6 = solve(Rad7_6(t) == R,t)/1e+6

end

I'd love some feedback on what is causing the issue.

 Age_638 = Age638(1/Data(n,1))/1e+6;

Age638 is not defined at that point. If it is a variable then it is very likely that your attempt to index it would be invalid.

Hi

Age638 and Rad7_6(t) are not defined. First defined these variable/ function in the code. Hope it will help.

And assign the result in the loop to Age7_6{n} and Age_638(n)
