I have this matrix in part a) called Mat1 and for part c) I need to do different arithmatic opertations to individual rows. How would I go about doing this? I can only seem to do it for the whole matrix.

Here's an example that adds 6 to the second row of a matrix M:

% define M
M = [1 2 3; 4 5 6; 7 8 9]
M = 3×3
     1     2     3
     4     5     6
     7     8     9
% add 6 to the second row of M
M(2,:) = M(2,:) + 6
M = 3×3
     1     2     3
    10    11    12
     7     8     9
