Some of these measurements have one dimension only — a magnitude — with no direction; these are called scalar quantities. In contrast, other measurements have a magnitude and a direction. These are called vectors. Hence, a vector is a scalar quantity with a direction. Examples of scalar ...
What is the Difference Between Scalar and Vector? A scalar quantity is a quantity that has only magnitude. Magnitude is another way of saying a numerical amount. Scalar quantities are quantities that don't require a direction to describe the meaning of the number. A direction isn't included ...

The product of two scalar quantities is a scalar, and the product of a scalar with a vector is a vector, but what about the product of two vectors? Is it a scalar, or another vector? The answer is, it could be either! There are two ways to take a vector product. One is ...
product is an operation on vectors that takes two vectors and produces a scalar, or a number. The vector dot product can be used to find the angle between two vectors, and to determine perpendicularity. It is also used in other applications of vectors such as with the equations of planes....
The addition of vectors and the subtraction of vectors uses the triangle law. Learn about vector addition and subtraction with the help of examples here.
Scalar Multiplication:The gradient of a scalar multiple of a function is equal to the scalar multiple of the gradient of that function. In mathematical terms: Directional Derivative:The dot product of the gradient of a function ∇f and a unit vector u gives the directional derivative of the ...
Additionally, it's important to know that ∇ is the del operator, a dot between two quantities (**X ∙ Y) shows a scalar product, a bolded multiplication symbol between two quantities is a vector product (X × Y), that the del operator...
If class weights are not provided, then no \ weighting is done (weight of 1 assigned to each class). Args: y_pred (tensor): Output of network (1D vector of class scores). Shape [numSamples x numClasses]. y_target (tensor): One-hot classification labels (1D vector). Shape [num...
It is not a vector because it does not have a directional component. Mass and speed are also two examples of scalar quantities.Algebra Rules for Scalars What Do Scalars Measure? Lesson Summary Register to view this lesson Are you a student or a teacher? I am a student I am a teacher ...
