In some cases, functions are provided for concepts or computations available elsewhere in R, but where the name is not obvious, e.g., R() for the rank of a matrix, or tr() for matrix trace. In other cases, we provide cover functions to show or demonstrate an algorithm in more detail, sometimes providing a verbose = argument to print the details of computations, e.g., Det() for a matrix determinant, Inverse() for a matrix inverse, using gaussianElimination() to show the steps. In addition, a collection of functions are provided for drawing vector diagrams in 2D and 3D, illustrating various concepts of linear algebra more concretely than has been available before. For example, showEqn(A, b) shows the matrix equations $\\mathbf{A x} = \\mathbf{b}$ in text or LaTeX form, while plotEqn(A, b) and plotEqn3d(A, b) plots those equations in 2D or 3D space. matrix2latex() , latexMatrix() , Eqn() and friends facilitate writing matrix equations in LaTeX. vectors() , vectors3d() plot geometric vector diagrams in 2D or 3D, with other functions to draw angles and arcs. regvec3d() calculates and plot vectors representing a bivariate regression model, lm(y x1 + x2) Installation 📦 Get the released version from CRAN: install.packages(\"matlib\"","default_branch":null,"files":null,"tree":[],"storefront":"/r/friendly","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/friendly/matlib/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
