FieldMatrix

The class is for matrix whose coefficient ring belongs field. It is a subclass of RingMatrix.

Constructor

FieldMatrix(row, column [, compo, coeff_ring])

row and column must be a positive integer. compo must be a list form. coeff_ring must be an instance of ring.Ring. In general, given matrix size and coefficient ring unspecified, you should call createMatrix for your profit.

Methods

toSubspace([isbasis])

Return the Subspace instance. It overrides the method from RingMatrix.

kernel()

Return the kernel of self.

image()

Return the image of self.

rank()

Return the rank.

inverseimage(V)

Return an inverse image of V by self.

solve(B)

Solve self * X = B. Return a particular solution and kernel of self.

columnEchelonForm()

Return the column echelon form.

Operators

operatorexplanation
M / dReturn the division of M by d. d must be scalar.
M // dReturn the division of M by d. d must be scalar.
