Description. The Vector Concatenate and Matrix Concatenate blocks **concatenate the input signals to create a nonvirtual output signal whose elements reside in contiguous locations in memory**. In the Simulink^{®} library, these blocks are different configurations of the same block.

The Vector product of two vectors, a and b, is denoted by **a × b**. Its resultant vector is perpendicular to a and b. Vector products are also called cross products. Cross product of two vectors will give the resultant a vector and calculated using the Right-hand Rule.

The simplest solution is to **use a copy constructor to initialize the target vector with the copy of all the first vector elements.** **Then, call the vector::insert function to copy all elements of the second vector**. We can also use only vector::insert to copy elements of both vectors into the destination vector.

Answer : According to the Parallelogram law of vector addition, if two vectors \vec{a} and \vec{b} represent two sides of a parallelogram in magnitude and direction, then their sum \vec{a} + \vec{b} = the diagonal of the parallelogram through their common point in magnitude and direction.

Product of vectors is of two types. A vector has both magnitude and direction and based on this the two product of vectors are, **the dot product of two vectors and the cross product of two vectors**. The dot product of two vectors is also referred to as scalar product, as the resultant value is a scalar quantity.

**Appending to a vector means adding one or more elements at the back of the vector**. The C++ vector has member functions. The member functions that can be used for appending are: push_back(), insert() and emplace(). The official function to be used to append is push_back().

Two types of multiplication involving two vectors are defined: the so-called **scalar product (or "dot product") and the so-called vector product (or "cross product")**.

**Vector Product of Two Vectors**

- If you have two vectors a and b then the vector product of a and b is c.
- c = a × b.
- So this a × b actually means that the magnitude of c = ab sinθ where θ is the angle between a and b and the direction of c is perpendicular to a well as b.

The graphical method of adding vectors A and B involves drawing vectors on a graph and adding them using the **head-to-tail method**. The resultant vector R is defined such that A + B = R. The magnitude and direction of R are then determined with a ruler and protractor, respectively.

Three methods are **parallelogram addition, triangular addition and direct addition**. The statement says that if two vectors are head to head or tail to tail or we can say they are adjacent side of parallelogram.

Draw the vectors one after another, placing the initial point of each successive vector at the terminal point of the previous vector. Then draw the resultant from the initial point of the first vector to the terminal point of the last vector. This method is also called the head-to-tail method .

Method 1: Tip to tail

Adding by the tip-to-tail method means **to move one vector so that its tail lies on the tip of the first vector**. The resultant vector, A+B - the sum of the two - is simply the new vector drawn from the origin of the first vector to the arrow of the second.

The resultant is **the vector sum of two or more vectors**. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.

**|A+B|=^1/2**. This is magnitude of resultant ( sum ) of vectors A and B. The maximum resultant occurs when the two vectors have the same direction.

Starting from where the head of the first vector ends, draw the second vector to scale in the indicated direction. Label the magnitude and direction of this vector on the diagram. Draw the resultant from the tail of the first vector to the head of the last vector. Label this vector as Resultant or simply R.

Electromotive force (EMF) is **equal to the terminal potential difference when no current flows**. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.

Career progression. At the beginning of their career, IAS officers receive district training with their home cadres followed by their first posting. Their initial role is as a **assistant collector cum sub-district magistrate** and they are placed in charge of a district sub-division.

**Unlike the MDGs, which only targets the developing countries, the SDGs apply to all countries whether rich, middle or poor countries**. The SDGs are also nationally-owned and country-led, wherein each country is given the freedom to establish a national framework in achieving the SDGs.

**To enhance access to Higher Education, ensuring equity, and in particular to the vulnerable sections of the society**. To frame policies and programmes for strengthening research & innovations and encourage higher educational institutions – public or private – to engage with industry and society.

The features of masonry include **design flexibility, various textures, structural strength, mold resistance, durability, simple maintenance needs and competitive cost**. Thanks to these properties, masonry has been one of the most used construction methods throughout history and in modern times.
