Homework Statement
Let L(x) a linear operator defined by setting the diagonal elements of x to zero. What will be the representation of this operator to the following basis set? x E X. X denote the set of all real symmetric 3x3 matrices.Homework Equations

The Attempt at a Solution
To get the question set right, I am assuming I am to find a linear operator whose functionality is as follows:
Brain storming: L(symmetric matrix) * Y( Any symmetric matrix) = X(matrix, whose diagonal is zero)...is this right? So Y has to be symmetric and L, Y and X has to be from the same basis. all I know is the basis set. Any hints please?
