Weaving machines are made up of parts called “warps” and each warp is divided into “blocks.” Warps have a fixed number of threads (say, 300). To produce the desired color blend pattern, a weaver needs to divide the warp into equal sized blocks: the first all purple with one green thread, the next all purple but with two green threads, followed by all purple with three green threads, and so on, until the last block is one purple thread followed by all green threads.... 478 Linear Algebra: An Introduction to Linear Algebra for Pre-Calculus Students Resource Type: Content Resource Discipline: Mathematics Ohio Standards Alignment: Grades 11–Postsecondary Professional Commentary: This online text in linear algebra covers all of the basic topics, plus Markov chains and least squares approximation.
