x1=sortrows(xf,2);
p=round(x1);
classes=20;
array=zeros(size(classes),3)
min1=min(p(:,2));
max1=max(p(:,2));
classwidth=(max1-min1)/classes;
d=ceil(classwidth);
sum=0; j=1;k=1;n=0;
lowerlimit=min1:d:max1;
cw=d-1;
upperlimit=cw+lowerlimit;
ll=lowerlimit';
ul=upperlimit';
for k=1:classes
for i=1:size(p)
if p(i,2)>=ll(k) && p(i,2)<=ul(k)
sum=sum+p(i,1);
end
end
array(k,1)=sum;
array(k,2)=ll(k);
array(k,3)=ul(k);
sum=0;
end
The error is in this line
Index exceeds matrix dimensions.
Error in ==> if p(i,2)>=ll(k) && p(i,2)<=ul(k)

Please use meaningful tags. Of course all questions in a Matlab forum concern "matlab".

You can use the debugger to check, what's going on:
dbstop if error
Then start the program again. When Matlab stops at the error inspect the values of i and k as well as the sizes of p, ll and ul.
It is not possible in theory that we can fix the problem, because all we have is the failing code, but we cannot guess its intention reliably.
