Wronskian

Wronskian[{y1,y2,…},x] gives the Wronskian determinant for the functions y1,y2,… depending on x.

Wronskian[eqn,y,x] gives the Wronskian determinant for the basis of the solutions of the linear differential equation eqn with dependent variable y and independent variable x. 

Wronskian[eqns,{y1,y2,…},x] gives the Wronskian determinant for the system of linear differential equations eqns.
