These arrays are then multiplied element by element as you passed times - a handle on the element-wise multiplication - as the first argument in the call to BSXFUN. Bfi 2 4 7. Displaystyle mathbf a circ mathbf b D_mathbf a mathbf b.

Copy to Clipboard. One way to perform the desired operation is to use a for loop to iterate through the third dimension of M1 and M2 and perform 2-D matrix multiplication at each level. A 2 3.

In other words given a vector with components V i and a matrix with components M ij Id like to output a new matrix W ij whose elements are W ij V j. I want to multiply each element of a vector with a matrix such that I end up with a 3D matrix or higher dimentions. Id like to be able to likewise multiply the rows or columns of a matrix by a vector V in the same sense.

In other words given a vector with components V i and a matrix with components M ij Id like to output a new matrix W ij whose elements are W ij V j M ij. Id like to be able to likewise multiply the rows or columns of a matrix by a vector V in the same sense.

For example if A is a vector and B is a. Given a vector V I can define an element-wise multiplication on another vector W as VW. Multiply a fi Object by a Scalar.

The size of the third dimension. Create a row vector a and a column vector b then multiply them. Create a 1-by-2 row vector and a 3-by-1 column vector and raise the row vector to the power of the column vector.
