In linear algebra, an inner product space is a vector space with an additional structure called an inner product. This additional structure associates each pair of vectors in the space with a scalar quantity known as the inner product of the vectors. Inner products allow the rigorous introduction of intuitive geometrical notions such as the length of a vector or the angle between two vectors. They also provide the means of defining orthogonality between vectors (zero inner product). Inner product spaces generalize Euclidean spaces (in which the inner product is the dot product, also known as the scalar product) to vector spaces of any (possibly infinite) dimension, and are studied in functional analysis.
An inner product naturally induces an associated norm, thus an inner product space is also a normed vector space. A complete space with an inner product is called a Hilbert space. An (incomplete) space with an inner product is called a pre-Hilbert space, since its completion with respect to the norm induced by the inner product is a Hilbert space. Inner product spaces over the field of complex numbers are sometimes referred to as unitary spaces.
Inner Product and Orthogonal Functions , Quick Example. In this video, I give the definition of the inner product of two functions and what it means for those functions to be orthogonal. I work a quick example showing that two functions are orthogonal.
It's the first video lesson in a series dedicated to linear algebra (second course).

The properties of inner products on complex vector spaces are a little different from thos on real vector spaces. We go over the modified axioms, look at a few examples, and tackle the complex Schwarz inequality.
In mathematics, the dot product or scalar product[1] (sometimes inner product in the context of Euclidean space, or rarely projection product for emphasizing the geometric significance), is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number. This video will show you how to perform dot product over two vectors.
Read your free e-book: http://hotaudiobook.com/mebk/50/en/B01KZE8138/book Partial Inner Product (pip) Spaces are ubiquitous, e.g. Rigged Hilbert spaces, chains of Hilbert or Banach spaces (such as the Lebesgue spaces Lp over the real line), etc. In fact, most functional spaces used in (quantum) physics and in signal processing are of this type. The book contains a systematic analysis of Pip spaces and operators defined on them. Numerous examples are described in detail and a large bibliography is provided. Finally, the last chapters cover the many applications of Pip spaces in physics and in signal/image processing, respectively. As such, the book will be useful both for researchers in mathematics and practitioners of these disciplines.

HUMBLE APOLOGIES : Our final part is slightly invisible. I will watch out for that in the oncoming videos.
Random inner product graphs form a special case of inhomogeneous random graphs. The model outline is that $n$ vertices are generated from a fixed distribution $\mu$ in $d$-dimensional space, and two vertices are connected with an edge with probability proportional to the inner product of their corresponding vectors. We show that, under the strong inner product condition, random inner product graphs with minimum degree $\Omega ({\log}^2 n)$ have constant conductance, with high probability. However: (1) Their conductance depends on $\mu$ and may differ from classical random graphs. (2)Their ΓÇ£sparsest cutsΓÇ¥ may involve sets of vertices of cardinalities much larger than the cardinalities of the sparsest cuts of classical random graphs. The above is in accordance with me...

When are vectors orthogonal? In this video you will learn about the innerproduct of vectors. With the inner product you can determine if vectors are orthogonal. You will also learn important properties of inner products. This prelecture video is part of the linear algebra courses taught at TU Delft.
Publicly Verifiable Inner Product Evaluation over Outsourced Data Streams under Multiple Keys Uploading data streams to a resource-rich cloud server for inner product evaluation, an essential building block in many popular stream applications (e.g., statistical monitoring), is appealing to many companies and individuals. On the other hand, verifying the result of the remote computation plays a crucial role in addressing the issue of trust. Since the outsourced data collection likely comes from multiple data sources, it is desired for the system to be able to pinpoint the originator of errors by allotting each data source a unique secret key, which requires the inner product verification to be performed under any two parties’ different keys. However, the present solutions either depend on ...

Continuing Lecture 33, I fix the proof of coordinate independence of the projection to begin. Then we study complex inner product spaces briefly. Symmetric and self-adjoint linear transformations are discussed. I SHOULD have called self-adjoing linear transformations "Hermitian operators" hence the result that the e-values of a Hermitian operator are real. Finally I sketched the proof of the spectral theorem. I hope I've shown enough for you to understand the proof in Damiano and Little. Next time I'll emphasize a couple points I missed in this Lecture (why complex matters for the existence of an e-value, and the more general topic of allowed coordinate change). Then we begin work on generalized e-vector theory aka Chapter 6 of Damiano and Little.
