Binary operations on matrices/vectors

This operator allows to do elementwise operation of two algebraic object i.e. matrices/vectors. There is one required condition to perform such operation: at least one domension values from both objects must be the same

a %m% b

a %d% b

a %-% b

a %+% b

Arguments

a	matrix/vector
b	matrix/vector

Value

Matrix/vector

Examples

# Multiply
m(1, 2, 3 | 4, 5, 6 | 7, 8, 9) %m% v(5,4,3)
#>      [,1] [,2] [,3]
#> [1,]    5   10   15
#> [2,]   16   20   24
#> [3,]   21   24   27
# Divide
m(1, 2, 3 | 4, 5, 6 | 7, 8, 9) %d% v(5,4,3)
