I dont have curve fitting toolbox so csacpi won't work.
if x = [Oct_17(1:30,2)]; y = [1:30];
What code do I used to plot and produce cubic spline ?

% fake data
x = sort(rand(1,5))
y = rand(size(x))
xmissing = linspace(0,1,1000); % put here coordinates of pts to be computed
ycomplete = interp1(x,y,xmissing,'spline');
plot(x,y,'or',xmissing,ycomplete,'-')
