I am working with mortality tables on MATLAB. My aim is to upload any (Mortality Table) data file in Matlab and calculate survival probabilities.
I tried to calibrate lifetable using MATLAB program [a,elx] = lifetablefit(x,lx). But I am not able to run the code. Matlab returns,
Unrecognized function or variable 'x'.
Error in lifetable (line 6) [a,elx] = lifetablefit(x,lx);
I have attached the datafile and I here is my code.
opts=detectImportOptions('lifetable2000CM.csv', 'PreserveVariableNames', true) % to locate table and return its import options
data = readtable('lifetable2000CM.csv',opts); % I have two variables "x" which is age and "lx" which is number of survivals at each age
[a,elx] = lifetablefit(x,lx);
MATLAB works perfectly fine if I write
load us_lifetable_2009
My aim is to to program any kind of lifetable in MATLAB. If anyone has experience in this area please help me out.

readtable() returns a table which should contain your variables. Try
[a,elx] = lifetablefit(data.x, data.lx);
