save data to a new row in a table for each iteration of a for loop
something like this might be useful for you: data=[]; for i=1:0.1:10 data(:,end+1)=[i^2;i^3];%just example of data end

Can't figure out what I am doing wrong. Looking to find square root using the equation given x=(x+x/a)/2. I also feel like I am not making use of the approximation errors ea and es.
just use this to solve x=(x+x/a)/2 a=input('') syms x xsol=vpasolve(x==(x+x/a)/2,x)

Index exceeds matrix dimensions error
You should use ( and ) not { and }. Try this code: t=zeros(10,1); for n=1:10 if n/2>2 t(n)=t(n-1)+1 end end
