How are computed the initial cost , result cost and the cost in general ?

[armoi...@gmail.com]

Hello All,
How are computed the costs: "Initial cost" and "final cost" ?

In Matlab, i computed the residual error using 2 programs coming from 2 programmers (i am on of them!) and the result is the same.
But the matlab result differs significantly from the cost computed in Ceres.

Many thanks

equation one is the expression for the cost returned by ceres.

are you accounting for the factor 1/2?

Thank you Sameer,
I have found the relation between the ceres result and my matlab result.
Very Best Regards
