Emulates the times() and .* operators from Matlab.
Arguments
- a
first factor of the multiplication
- b
second factor of the multiplication
Value
matrix with dimensions equal to the larger of the two factors
Details
This function basically handles elements of different length
better than the * operator in R, at least as far as behavior from a
Matlab user is expecting.
Examples
times(9, 6)
#> [,1]
#> [1,] 54
x <- matrix(1:4, 2)
y <- c(10, 3)
print(x)
#> [,1] [,2]
#> [1,] 1 3
#> [2,] 2 4
print(y)
#> [1] 10 3
times(x, y)
#> [,1] [,2]
#> [1,] 10 30
#> [2,] 6 12
x * y
#> [,1] [,2]
#> [1,] 10 30
#> [2,] 6 12
