6.47.12 Kernel of a linear function: kernel nullspace ker
The ker command finds a basis for the kernel of a linear
function.
kernel and nullspace are synonyms for ker.
-
ker takes one argument:
A, a matrix representing a linear function with respect to the
standard basis.
- ker(A) returns a list of vectors that is a basis of
the kernel of the linear function.
Example.
Input:
ker([[1,1,2],[2,1,3],[3,1,4]])
Output:
