FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS using SINC-COLLOCATION PROCEDURE

Hi, I am using MATLAB R2007b to compile an M-file(filename = divine) program that comfortably generate solution for the above title. I called the function from another M-file(script) using a for-loop and I got the desired solution. But when I try to pick some of the generated data for plotting using the function 'gather', it shows the following error:

"Undefined method 'gather' for input argument of type double' .

I tried using DISTRIBUTED COMPUTING TOOLBOX with Parallel Mode with 4 labs and I still got the same error.

How do I fix this problem? I have attached the the script I used to invoke the M-file.

alpha = 1; a = 1; b = 1; d = 3.14; x = 1; t = 1; lamda = 0.5; i = 1; j = 1;

for N = drange(5,5,50) [h,phi1,phi2,Wi,wi,Wj,wj,tj,m,n,p,r,K1,K3,K2,Kn,En,Un,E,S,Use] = divine(alpha,d,a,b,i,j,x,t,lamda) end

Check with ver that the Parallel Computing Toolbox is listed, if not it is not installed.
