hi
This code runs in the matlab 2009a version. But the code does not run in the matlab 2013a version, and error messages are.

I deduce from that message that in the expression segm(p).regs(:,:,rix)*rix that rix must be an integer data type, such as int32, and that segm(p).regs must be a different integer data type, such as uint8
At the MATLAB command line give the command
dbstop if error
and run the program. When it stops, have it display
class(rix)
class(segm(p).regs)
class(segm(p).all)

Yes, I get the following output:
>> class(rix)
ans = uint8
>> class(segm(p).regs)
ans = logical
>> class(segm(p).all)
ans = double
The issue seems to be with *rix, so I changed it to this, which seems to solve the problem:
segm(p).all = segm(p).all + segm(p).regs(:,:,rix)*double(rix);
