is a function from natural numbers to vectors. Correspondingly, is the value of that function at n - 1.
I require some help in understanding whats going on here. THanks.
I dont understand what is the use of Un-1 ? what is meant by (n-1) please explain.
The standard form of linear recurrence relation in vector/matrix form is Un=AUn-1, where A is kxk matrix.
Un=(xn ;yn ;zn)
and hence obtain a paticular solution
