MATLAB: How to Add Headings to a list of data

array

Here is the code I have.
function[root,ea,iter]=secant(func,delta,xr,es,maxit,varargin)
if nargin<3,error('atleast 3 input arguments required'),end
if nargin<4|isempty(es),es=0.0001;end
if nargin<5|isempty(maxit),maxit=50;end
iter=0;
T=[]
while (1)
    xrold=xr;
    xr=xr-((delta*xr*func(xr))/(func(xr+(delta*xr))-func(xr)));
    iter=iter+1;
    if xr~=0, ea=abs((xr-xrold)/xr)*100;end
    if ea<=es|iter>=maxit,break,end
  funcxr=func(xr); 
  T=[T;[iter,xr,func(xr),ea]];
end
T
root=xr;
Here is the output.
>> secant(@(x) 6*x^2-13*x-5,10^-6,1.2)
T =
     []
T =
    1.0000    9.7428  437.8779   87.6832
    2.0000    5.5290  106.5398   76.2143
    3.0000    3.5319   23.9303   56.5448
    4.0000    2.7174    3.9799   29.9710
    5.0000    2.5145    0.2472    8.0718
    6.0000    2.5001    0.0012    0.5757
    7.0000    2.5000    0.0000    0.0029
ans =
    2.5000
I need to have headings on the top of the colmuns and have no clue how to add them. Please help

If you have R2013b or later, use a table. The documentation explains how to specify and add the variable names. Note that if you have R2019b or later, the variable names do not need to be valid MATLAB identifiers.
