error 'Index exceeds matrix dimensions.'

I want to compute the following code but an error which says 'Index exceeds matrix dimensions' appears and I find it puzzling. More to this the 'jj' which suppose to 25 become '1' and 'tcal' changes from 26 to 25.. Here is the code
for ii = 1:length(datafiles);
%%files will be loaded here%%
tcal = max(min(time),min(hTime)):dt:min(max(time),max(hTime));
Sca1 = interp1(time,ssc,tcal);
x= cast(calpre, 'double');
kk=1:1:length(x);
B=repmat(reshape(x(kk),1,1,length(x)),20,40);
M=M(:,:,3);
M1 = permute(M*1000,[2 1]);
M2= interp1(hTime,M1,tcal);
for jj = 1:length(tcal);
h2(:,:,jj)=h(:,:,jj)-B(:,:,jj).*0.001;
sig2(:,:,jj)=sig1(:,:,jj).*(h2(:,:,jj)./h(:,:,jj));
C(:,:,jj) = max(sig2(:,:,jj),[],1
Sca1l = permute(Sca1 ,[3 2 1]);
Sca13(:,:,jj)=interp1(sig1(:,1,jj),Sca1l(:,:,jj),C(:,jj)');
end
end
Any help is highly appreciated

The DBSTOP command is good for finding errors like these.

'Index exceeds matrix dimensions.' is nothing too mysterious. It happens when you do things like this:
>> x=1:5
x =
1 2 3 4 5
>> x(6)
Index exceeds matrix dimensions.
