MATLAB: Changing specific rows of a logical matrix

MATLABmatrix manipulation

I have a vSlice=MxN logical matrix. I want to be able to review the first row, last row, first col and last col for "1's" and convert them to "0's". I believe the lines below will pull out the relevant data. I am looking to change the rows without making any new variable. Thank you.
      %test border rows columns
      endcol=vSlice(:,end);
      endrow=vSlice(end,:);
      col1=vSlice(:,1);
      row1=vSlice(1,:);

Best Answer

vSlice([1,end],[1,end])=0;
