MATLAB: Levenberg–Marquardt algorithm with fixing the last row of solution

Question

Hi all, I am using Levenberg–Marquardt algorithm to do an optimization(I use lsqnonlin function). In fact I want to get a solution that I fix its last row. In fact my solution has this following forme :

    X=[ x11 x12 x13 x14 ;
    x21 x22 x23 x24 ;
    x31 x32 x33 x34 ;
    0    0   0   1  ]

So I want to get a solution using Levenberg–Marquardt with fixing its last row to [0 0 0 1] Any help please ?

Answer 1

g = @(x) YourFunction( reshape([reshape(x, 3, 4); 0 0 0 1], [], 1) )

then optimize g
