WebShort answer - yes, Absolutely! Longer answer - You can view scalar division as multiplying by the reciprocal [i.e dividing a number/matrix by a set number is the same as multiplying by 1/number] For example: 15/3 … WebYou can write this definition using the MATLAB ® colon operator as C (i,j) = A (i,:)*B (:,j) For nonscalar A and B, the number of columns of A must equal the number of rows of B . Matrix multiplication is not universally commutative for nonscalar inputs. That is, A*B is typically not equal to B*A.

WebFor example, if A is a matrix of order 2 x 3 then any of its scalar multiple, say 2A, is also of order 2 x 3. Matrix scalar multiplication is commutative. i.e., k A = A k. Scalar multiplication of matrices is associative. i.e., (ab) A = a (bA). The distributive property works for the matrix scalar multiplication as follows: k (A + B) = kA + k B. WebInput, specified as a number, or a symbolic number, scalar variable, matrix variable, function, matrix function, expression, or vector, matrix, or array of symbolic scalar variables.
