WebNotation for element-wise division of vectors. I am wondering if there is any standard notation for the element-wise division of vectors. I am going to use ⊘ for this purpose, similar to ⊙ that is used in some texts for element-wise multiplication. For example, assuming u → and v → are vectors of length k, then x → = u → ⊘ v → ... WebMatrix Mode. When the value of the Multiplication parameter is Matrix(*), the Product block is in Matrix mode, in which it processes nonscalar inputs as matrices.The MATLAB equivalent is the * operator.
