Multiply

Multiplies two variables. It returns the product of x and y. If one argument is a vector, the other one must not be a signal.

x*y

	Variable Name	Value Type	Variable Type
Arguments:	x	real, complex	scalar, vector, matrix, signal, xy-data
Arguments:	y	real, complex	scalar, vector, matrix, signal, xy-data
Result:	z	real, complex	scalar, vector, matrix, signal, xy-data

Use the X button to complete the operation.

Multiply Scalar and Vector

ID	Description	Type	Value	Expression
x	Argument	REAL VECTOR		[2, 2.5]
y	Argument	REAL	3	3
z	Result	REAL VECTOR		x*y

Multiply Vector and Vector (Same Length)

ID	Description	Type	Value	Expression
x	Argument	REAL VECTOR		[2, 2.5]
y	Argument	REAL VECTOR		[3, 3.5]
z	Result	REAL	14.75	x*y

Also known as scalar product or inner product.

Multiply Vector and Matrix

ID	Description	Type	Expression
x		REAL VECTOR	[1,2]
y		REAL MATRIX	[[2, 2.5, 3],[3.5, 4, 4.5]]
z	Result	REAL VECTOR	x*y

ID	Description	Type	Expression
x	Argument	REAL MATRIX	[[2, 2.5, 3],[3.5, 4, 4.5]]
y	Argument	REAL VECTOR	[1,1,1]
z	Result	REAL VECTOR	x*y

Multiply Matrix and Matrix

The number of columns in x must be equal to the number of rows in y.

ID	Description	Type	Expression
x	Argument	REAL MATRIX	[[1,2],[3,4],[5,6]]
y	Argument	REAL MATRIX	[[1,2,3],[4,5,6]]
z	Result	REAL MATRIX	x*y

Multiply Matrix and Signal

The number of columns in x must be equal to the number of channels of y. The result is a signal and has as many channels as the matrix has rows.

ID	Description	Type	Expression
x	Argument	REAL MATRIX	[[1,2],[3,4]]
y	Argument	REAL SIGNAL	signal([0,0.5,1],[1,2,3],[1,2,3])
z	Result	REAL SIGNAL	x*y

Multiply Signal and Signal

ID	Description	Type	Expression
x	Argument	REAL SIGNAL	signal([0, 0.5, 1],[1, 2, 3])
y	Argument	REAL SIGNAL	signal([0, 0.5, 1],[2, 3, 4])
z	Result	REAL SIGNAL	x*y
