List Of Matrix Multiplication In R References
List Of Matrix Multiplication In R References. Multiplies two matrices, if they are conformable. The previous operations were done using the default r arrays, which are matrices.
If one argument is a vector, it will be promoted to either a row or column matrix to make the two arguments conformable. Byrow is a logical clue. The syntax of the expression to multiply matrices a and b is.
