brk2knt - Convert breaks with multiplicities into knots
Syntax
[knots,index] = brk2knt(breaks,mults)
Description
[knots,index] = brk2knt(breaks,mults) returns
the sequence knots that is the sequence breaks but
with breaks(i) occurring mults(i) times,
all i. In particular, breaks(i) will
not appear unless mults(i)>0. If, as one would
expect, breaks is a strictly increasing sequence,
then knots contains each breaks(i) exactly mults(i) times.
If mults does not have exactly as many entries
as does breaks, then all mults(i) are
set equal to mults(1).
If, as one would expect, breaks is strictly
increasing and all multiplicities are positive, then, for each i, index(i) is
the first place in knots at which breaks(i) appears.
Examples
The statements
t = [1 1 2 2 2 3 4 5 5];
[xi,m] = knt2brk(t);
tt = brk2knt(xi,m)
give [1 2 3 4 5] for xi, [2
3 1 1 2] for m, and, finally, t for tt.
