linearComb(L,varName)
This routine produce a generic linear combination of the elements in L. It can be used together with genKer or genIm to solve a system of homogeneous linear equations.
In this example we compute a generic and a particular linear combination of two particular differential 2-forms.

In this example we compute a generic differential 1-form that descends to the projective plane. Then, we impose another linear condition.
