You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: wronskian.m
    path of file: ./repos/chebfun/@linop
    
    the code of the file until where you have to start completion: function w = wronskian(L, varargin)
%WRONSKIAN   Wronskian of chebfuns.
%   WRONSKIAN(L, f1, ..., fn) computes the wronskian of the CHEBFUN objects fk.
%   L is the linear differential operator and f1, ..., fn are solutions of the

    
function w = wronskian(L, varargin)
%WRONSKIAN   Wronskian of chebfuns.
%   WRONSKIAN(L, f1, ..., fn) computes the wronskian of the CHEBFUN objects fk.
%   L is the linear differential operator and f1, ..., fn are solutions of the
%   homogenous problem. The algorithm is based on Abel's identity for computing
%   the wronskian.
%   
%   WRONSKIAN(L, F) does the same where F is a quasimatrix or an array-valued
%   CHEBFUN or a CHEBMATRIX. If F is a CHEBMATRIX, then the form of F is assumed
%   to be a CHEBMATRIX with a single column with n CHEBFUNs.
