how to eliminate the error

>> %input, generating 13 points on curve >> x=[-50 -41.2 -34.2 -27.13 -18.05 -6.94 -1.93*10.^(-33) 12.31 22.5 32.69 41.86 46.9 51.02];

>> y=[-5 -1.66 0.36 2.04 3.64 4.77 5 4.76 4.09 2.99 1.64 0.74 -0.0698];

>> %spline that interpolates (x,y) >> s=spline(x,y)

s =

      form: 'pp'
    breaks: [1x13 double]
     coefs: [12x4 double]
    pieces: 12
     order: 4
       dim: 1

>> %first derivative,pp form

>> s1=s; >> s1.order=s.order-1

s1 =

      form: 'pp'
    breaks: [1x13 double]
     coefs: [12x4 double]
    pieces: 12
     order: 3
       dim: 1

>> s1.coefs=bsxfun(@time,s1.coefs(:,1:end-1),s1.order:-1:1) ??? Error using ==> bsxfun Undefined function 'time' for input arguments of type 'double'.

what does this error means and how to solve it...??

Can any one help me.. in going furthest to find curvature

@time ===> @times

s1.coefs=bsxfun(@times,s1.coefs(:,1:end-1),s1.order:-1:1)
