Details:
The following lines where giving no errors in Octave 3.2.4 (Ubuntu 10.10)
x = linspace(0,1,10);
y = sin(2*pi*3*x);
pp = spline(x, y);
xi = 0:0.3:1;
yi = ppval(pp,xi);
ppd = fnder(pp,1);
dyi = ppval(ppd,xi);
In 3.3.54 and the repository version the last line gives the following error
error: ppval: A(I,J,...): index to dimension 2 out of bounds; value 9 out of
bound 8
error: called from:
error: ppval.m at line 69, column 4
If I change xi for
xi=linspace(0,8/9-eps,10);
then
dyi = ppval(ppd,xi);
works fine
