Kernel vector of statics Jacobian

  1. Jan 9, 2015 #1
    Hi all,

    I was reading an article that utilized a 3x4 statics Jacobian and said to calculate the kernel vector:
    You can row by row, where

    Where Ai is the statics Jacobian with the ith column removed. The problem is I have a 3x3 statics Jacobian, so if I remove the ith column I will end up with a non-square matrix, which means taking the determinant would not be possible. Is there another way to find the kernel vector in a similar way? Could I not remove the column?

    You are using specialized terminology and it's unclear what your column vector represents. It would help if you gave a link to the article you mention or show a relevant passage from it. Are you working a problem in "statics", as in physics?
