Arguments

e1, e2

first and second operands

Details

Both operands can be:

• numerical scalar

• polynomial scalar

• numerical matrix

• polynomial matrix

Value

Unary + return same object.

Binary + with two matrix operands returns elementwise summation.

Binary + with matrix and scalar operands returns elementwise summation with scalar.

Binary * is elementwise multiplication with matrix or scalar operands.

Unary - return a matrix with changed sign.

Binary '-' of matrices or scalar operands returns matrix subtraction.

Functions

• +,polyMatrix,missing-method: unary +

• -,polyMatrix,polyMatrix-method: unary -
