Can anyone explain what is the mathematical operation for C = A/B where A and B are both row vectors? >> A = [1 2 3 4] >> B = [2 2 2 2] >> C = A/B C = 1.2500 As you can see, C*B is not equal to A. This suggest that / is not a matrix right division. It al...

for better understanding i recommend reading on matrix divide. see for example:Division
Divide Row and Column Vectors Copy Code Copy Command Create a 1-by-2 row vector and 3-by-1 column vector and divide them. Get a = 1:2; b = (1:3)'; b .\ a ans = 3×2 1.0000 2.0000 0.5000 1.0000 0.3333 0.6667 The result is a 3-by-2 matrix, where each (i,j) element...
