Equation 5: 2 x 2 Matrix … WebSep 17, 2024 · Let’s look at the matrices we’ve formed in this example. First, consider \(AA^{T}\). Something seems to be nice about this matrix – look at the location of the 6’s, the 5’s and the 3’s. More precisely, let’s look at the transpose of \(AA^{T}\). We should notice that if we take the transpose of this matrix, we have the very same ...
WebWe can multiply a matrix by a constant (the value 2 in this case): These are the calculations: We call the constant a scalar, so officially this is called "scalar multiplication". Multiplying … WebSep 16, 2024 · Theorem 3.2. 1: Switching Rows. Let A be an n × n matrix and let B be a matrix which results from switching two rows of A. Then det ( B) = − det ( A). When we switch two rows of a matrix, the determinant is multiplied by − 1. Consider the following example. Example 3.2. 1: Switching Two Rows.
