store array into matrix

i've divided the image into overlapping blocks of size 2x2.

 overlapR=(rows-(blockSizeR-1));
 overlapC=(columns-(blockSizeC-1));
 BmatRows=(rows-(blockSizeR-1))*(columns-(blockSizeC-1));
 BmatCols=blockSizeR*blockSizeC;

 index=1;

 newB=zeros(BmatRows,BmatCols);
 for row=1:incrR:rows-(blockSizeR-1)
        rowStart=row;
        rowEnd=row+(blockSizeR-1);

    for col=1:incrC:columns-(blockSizeC-1)
        colStart=col;
        colEnd=col+(blockSizeC-1);
        dbstop if error

        oneBlock=grayImage(rowStart:rowEnd,colStart:colEnd);

        blurMoment=BlurInvariants(oneBlock);

        newB(index,:)=blurMoment;
        index=index+1;
     end
end

next i calculated the BlurInvariant (I1 to I6 moments) its output is

    Columns 1 through 4

55.578300091237828  80.214628323890793  63.941635242249006  67.963797222206097

Columns 5 through 6

81.296646744833296   7.960173582309505

the following error occurs

Subscripted assignment dimension mismatch.

 Error in overlapLexicoBlurInvariant (line 72)
        newB(index,:)=blurMoment;

plz help me solving my error

The size of newB and blurMoment do not match. What sizes do you get, when the deugger stops at the error?
