WebFor an orthogonal matrix R, note that det R T = det R implies (det R) 2 = 1, so that det R = ±1. The subgroup of orthogonal matrices with determinant +1 is called the special orthogonal group, denoted SO(3). Thus every rotation can be represented uniquely by an orthogonal matrix with unit determinant. WebFor example multiplication by $2$ on $\Bbb{C}$ has determinant two (it's a 1x1 matrix $2I_1$), but when we view $\Bbb{C}$ as $\Bbb{R}^2$ it is a 2x2 matrix $2I_2$ with determinant $=4$. $\endgroup$ – Jyrki Lahtonen

WebExample 1: Calculate Determinant of Matrix Using det () Function. In this section, I’ll illustrate how to apply the det function to calculate the determinant of a matrix object in … WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A).
