linalg(deprecated)

 wronskian
 wronskian matrix of a vector of functions

 Calling Sequence wronskian(f, v)

Parameters

 f - vector or list of expressions v - variable

Description

 • Important: The linalg package has been deprecated. Use the superseding command VectorCalculus[Wronskian], instead.
 - For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.
 • The procedure wronskian(f, v) computes the wronskian matrix of f with respect to v. The (i,j)th entry of the matrix result is $\frac{{\partial }^{i-1}}{\partial {v}^{i-1}}\phantom{\rule[-0.0ex]{0.4em}{0.0ex}}{f}_{j}$. The wronskian determinant is the determinant of the wronskian matrix.
 • The command with(linalg,wronskian) allows the use of the abbreviated form of this command.
