You can not do it when v=11:99.
If you want to convert to 9x9 matrix, then you need to have 81 elements in your vector, with this you have 89. If you define it as v=11:91, then the following command will do what you want.
v=reshape(v,9,9)

v=11:99;
IND=find(mod(v,10)==0);
v(IND)=[];
v=reshape(v,9,9)
