acessing a range in a matrix?

x=10x10

x1=x(:,[5:7 9:10]);

 %it means your new matrix x1 consist of matrix all rows(:) and a column 
  range of 5-7 and 9-10

Addresses are row, column

   x=m(1400:1500,1);

Simply put the numeric range in with the colon operator for rows or columns as desired.

and then you're on your way w/ under the "MATLAB" button.
