HOW TO CALCULATE LINE BY LINE

Hello Every one ; I have a matrix A of a 6*7 elements

A11 A21 A31 A41 ...    
A12 A22 A32 A42 ...      
A13 A23 A33 A43 ...
.   .   .   .  ...

if I want to make a for loop but I want to calculate line by line : I mean : I want to calculate : A11, A12, A13...after go to the second column calculate : A21,A22,A23, after go to third column calculate : A31,A32,A33 ....

If I put the loop

[s z]=size(A)

for i=1:s-1
for j=1:z
for y=2:s
B(i,j)=A(i,j)+cosd (A(y,j))
end 
end
end

How can I calculate line by line ? Calculates first line of elements, then second line of elements then third ...as explained before ?

Thank you in advance

Perhaps this helps already:

A = rand(3,4);
for iLine = 1:3
  disp(A(iLine, :))
end
