Error while running autocalib_test.m

Hi I got this error while running autocalib_test.m

Error using  {} 
Subscripting into a table using one subscript (as in t(i)) is not supported. Specify a row subscript and a variable subscript,
as in t(rows,vars). To select variables, use t(:,i) or for one variable t.(i). To select rows, use t(i,:).

When I tried changing KeyValDb/check (line 102) it raised consecutive errors.
What could be the solution to this?
Thank you.

I've encountered same problem. AS i understand, those guys used older matlab version and something has changed in matlab since they pushed this code.

I've beat that problem by changing if v{1} == 1 to if v{1, 1} == 1 (v is the table and matlab asks to acces element of table using two indexes, not one). But that's not the only problem unfortunately...

I tried the same fix, but there are too many consecutive fixes you would have to apply. I tried using ubuntu 14.04 and an older version of MATLAB. Perhaps you guys could suggest a MATLAB version used at the time this code was created?

[DaddyWesker]

I was able to launch this autocalib_test.m using Linux Mint 20 and Matlab R2020a.

[alexvbogdan]

Oh, thanks a lot! Did you apply lots of fixes? And if you did, could you perhaps open a PR here with your version of the code or provide a link to another repo?

[DaddyWesker]

Actually, I've made no changes in the code. Just installed Matlab R2020a. I've though needed to do some changes in matlab libs. If you'll encounter problem with libstdc++.so.6 and just found this solution to fix this .
