Details:

all the unit tests in tps_val.m worked in version 1.2.8 of the splines
package.  In version 1.2.9, the first unit test fails:


octave:2> pkg load splines
octave:3> test tps_val
***** assert (tpaps(x,y,1,x), tps_val(x,c,x));
 x = rand(100, 2)*2 - 1; 
 y = x(:, 1) .^ 2 + x(:, 2) .^ 2;
 c = tpaps(x,y,1);
!!!!! test failed
ASSERT errors for:  assert (tpaps (x, y, 1, x),tps_val (x, c, x))
