[OctDev] bug in csape (part of package splines)

[Ted R. <ted...@gm...>]

csape(x, y, "cond") with a boundary condition of "periodic" will work  
for a one dimensional vector, but not for a matrix value for y. This  
is fixed by changing line 162 in csape.m from:

   c(2:n,idx) = z(:,2:end) - z(:,1) * fact;

to:

   c(2:n,:) = z(:,2:end) - z(:,1) * fact;
