MATLAB: How could I extract last column in a matrix if I don’t know the size of matrix

matrix manipulation

I want to select only last coloumn..because in my program the size of matices is change every time..these are some example of my matices

(150×23)

(150×34)

(150*41)

…etc

matrix(:,end)

The "a" values are simply being used as row numbers for indexing into b.

b(a(:),:)

= b([1;2;1;2],:)

which is equivalent to

[ b(1,:);
  b(2,:);
  b(1,:);
  b(2,:)]

newcellarray = num2cell(reshape(yourcellarray.', size(yourcellarray, 2), 43, []), [1 2]); 
newcellarray = vertcat(newcellarray{:})
