WebSimilar Matrices We begin with the algebraic definition of similarity. Definition Two n × n matrices A and B are similar if there exists an invertible n × n matrix C such that A = CBC − 1 . Example Example As in the above example, one can show that I n is the only matrix that is similar to I n , and likewise for any scalar multiple of I n . WebMar 5, 2010 · I have a circular geometry which is discretised by triangular elements. Now suppose the total number of triangle is 4 with 3 nodes like T=[1 2 3;6 5 8;8 11 4;10 3 12] and boundary nodes are B=[1 3 5 10 12].Now boundary condition for each boundary node of a triangle Q=7.5 and size of Q is 3x3. Webreferred to a different coordinate system (or basis). Thus any two matrices that are similar to each other represent the same point transformation in n-space i.e. they map points in the same way, they represent the same linear point transformation.
