Partitioned mobile vector inner product and matrix multiplication demonstrator

Abstract

The invention discloses a partitioned mobile vector inner product and matrix multiplication demonstrator and aims to solve technical problems that a matrix formula cannot be quickly constructed in theprior art or a device mentioned in the background art, the vector inner product and matrix multiplication operation process cannot be visually represented, and data change of the specific site cannotbe automatically completed. The partitioned mobile vector inner product and matrix multiplication demonstrator is characterized by comprising a demonstrator support, at least one character generator,a left matrix constructor, an inner product processor, a right matrix constructor, a result synthesizer, two spotlights, at least one right-angled reflector and at least one photoelectric controller.The partitioned mobile vector inner product and matrix multiplication demonstrator is advantaged in that linear and multiplication operations of a four-bit integer element matrix can be completed, inner product operation of a four-bit integer component vector can be completed, the demonstrator is convenient to carry and has strong applicability, the structure is compact, and edit calculation demonstration in multiple types of occasions in any visual angle can be carried out.

Description

technical field [0001] The invention relates to a device capable of constructing and dissecting handwritten matrix formulas by demonstrating the whole process of matrix linear operation, multiplication operation, and vector inner product by means of electronically controlled transmission, automatic display of characters, and orthogonal correspondence of rows and columns. Process the series of data changes that occur during operations when the elements or components are four-digit numbers (including three-digit positive and negative numbers, fractions, and decimals). A partitioned mobile vector inner product and matrix multiplication demonstrator suitable for teacher teaching, student learning, formation drills, etc. Background technique [0002] The matrix addition and subtraction multiplication, matrix product and vector inner product in the linear algebra courses of colleges and universities are the basis for mastering matrix theory and linear space. There are many element...
