Arguments

e1, e2

One of the operands need to be a FlashR object. If one operand is a matrix and the other is a vector, we perform the arithmetic operation on the vector and every column of the matrix. If one operand is a scalar, we perform the operation on the scalar with every element in the matrix or the vector.

There are a few exceptions. For example, the left operand of "^" has to be a FlashR object and the right operand has to be a scalar.

Examples

mat1 <- fm.runif.matrix(100, 10)
mat2 <- fm.runif.matrix(100, 10)
mat <- -mat1
mat <- mat1 + mat2
mat <- mat1 - mat2
mat <- mat1 * mat2
mat <- mat1 / mat2
mat <- mat1 ^ 2
