Description
|
|
|
•
|
The procedure kernel computes a basis for the null space (kernel) of the linear transformation defined by the matrix A. The result is a set of vectors, possibly empty.
|
|
•
|
When given an optional second parameter, kernel(A, 'nulldim'), in addition to the above, assigns the variable nulldim the vector space dimension of the kernel (a non-negative integer).
|
|
•
|
The command with(linalg,kernel) allows the use of the abbreviated form of this command.
