The warning message means that you are trying to invert a singular matrix. Use
>>dbstop if warning
and then re-run to trap the occurrence of this and see if you generated the matrix that you intended.
The error message means that you are trying to do a subscripted assignment, like below, where the right and left sides do not match in size
>> a=rand(3); b=rand(3,3,2);
>> a(1:2,:)=b(1:2,:,:)
Assignment has more non-singleton rhs dimensions than non-singleton subscripts
The usual way to trap these is likewise with the debugger
>> dbstop if error

@Bishow: Exactly. RHS means "right hand side". The dimensions on both sides of the equal operator do not match.
