A pseudoinverse for Frank's formula.
In a previous communication, it has been argued that in the Frank-Bilby equation and in the o-lattice equations a pseudoinverse must be used when the reduced displacement-field matrices are not invertible. Here an explicit expression for the pseudoinverse of Frank's formula is derived using a direct vector approach.
