I am trying to use downloaded code.(GGcall)

clear all
close all
colors={'r.' 'gx' 'b+' 'ys' 'md' 'cv' 'k.' 'r*' 'g*' 'b*' 'y*' 'm*' 'c*' 'k*' };
%the data
data.X=load('a.dat');
%normalization
data=clust_normalize(data,'range');
%parameters
param.c=8;
param.m=2;
param.e=1e-3;
param.val=1;
param.vis=0;
%Gath-Geva clustering
result = kmeans(data,param);
param.c=result.data.f;
result = GGclust(data,param);
%validation
result = validity(result,data,param);
plot(data.X(:,1),data.X(:,2),'b.',result.cluster.v(:,1),result.cluster.v(:,2),'ro');
hold on
plot(result.cluster.v(:,1),result.cluster.v(:,2),'ro');
%evaluation
new.X=data.X;
eval = clusteval(new,result,param);
result.validity

SO I got this: ??? Undefined function or method 'isnan' for input arguments of type 'struct'.

Error in ==> statremovenan at 29

[ignore,wasnan,X] = statremovenan(X);
Error in ==> GGcall at 19
result = kmeans(data,param);
