v2.5 2025-05-16
- least norm is replaced by minimizing the norm of n-th derivative
coeffs in under-determined systems
- dmat() gains a new parameter
nderiv
- fixed flate tv curve in iknots()
v2.4 2025-03-12
- added abcisse range check for arguments in equality constraints of
smbsp()
- iknots: tv can be smoothed for xki finding
- iknots: tv is smoothed till at least one x point belongs to each
knot interval
- iknots: if lenfit is 0, all tv values are used for linear
interpolation
- smbsp: outside or border xki are now removed with warning, not
error
- [fit]smbsp: added
regular_grid parameter
- fitsmbsp: default precision in xki fit is 0.01dx instead of
0.1dx
- fitsmbsp: minimal distance imposed between knots is now dx, not
dx/10
- par2bsp: if select parameter is NULL, it is considered as
missing
v2.3.0 2025-02-05
- added imat(), integration matrix computation
- fixed dmat() for nqw
- fixed extra quotes in
bspline manual
- added parameter ‘lenfit’ to iknots()
v2.2.2 2024-07-02
- fixed typo in example of
pbsc()
- fixed syntax error in manual for
bsc() and
bsp()
- fixed missing variable in test of example for
pbsc()
- fixed missing export for
pbsc()
v2.2.1 2023-05-30
- fixed typo in rgl example of
bcurve()
- fixed NEWS mention of
parr() for v2.2.
- added
pbsc()
v2.2 2023-05-26
- added
bcurve() for building nD curves from a set of
control points
- added
parr() polynomial formulation of B-splines
v2.1 2022-09-26
smbsp() can estimate covariance matrix of estimated
coefficients- added
dmat() for differentiation operator
ipk() is now exported and tested- fixed 0-value for abscissas on the right hand side of the knot
interval
v2.0.1 2022-04-19
bsc() can calculate Jacobian of basis vectors as
function of knots. By consequence, the suggestion of
numDeriv package is removed- added
jacw() calculating Jacobian of B-spline with
weights
- added
ibsp() for integration
- now,
iknots() can deal with repeated x
values
- added monotonicity and positivity optional constraints
- added Copyright field to DESCRIPTION
- fixed inequality generation in
fitsmbsp()
- fixed gcc-12 compile error
v1.0.2 2022-03-17
- fixed ipk() ASAN problem signaled by R CRAN team
- fixed export of
par2bsp()
- fixed error in example of
fitsmbsp()
- fixed debug printing in
iknots()
- increased resolution from 5 to 10 intervals for tv fitting by linear
B-splines in
iknots()
- forced monotonicity in
iknots() despite possible
round-off errors
- added URL and BugRepport in DESCRIPTION
v1.0.1 2022-03-11
