在 MATLAB Online 中打开

z = magic(5);

I need to add the elements of the third row to the elements in the fifth row while the third row remains unchanged.

 z =
  24     1     8    15
   5     7    14    16
   6    13    20    22
  12    19    21     3
  18    25     2     9

Hints:

The i'th row of a matrix z is z(i,:)

The j'th column of a matrix z is z(:,j)

@Carter.....you need to learn basics of MATLAB first rather then posting simple questions. MATLAB is a easy software with rich documentation..if you spend few minutes of time on documentation, you can achieve your task on your own. Later when you face complex situations in mere future, you can take use of this community. Read this link first:
