Let's see the steps to find the determinant of a matrix. Initialize the matrix. Write a function to find the determinant of the matrix. If the size of the matrix is 1 or 2, then find the determinant of the matrix. It's a straightforward thing. Initialize variables for determinant, submatrix, sign. Iterate from 1 to the size of the matrix N.

Let $ \lambda_1 \le \lambda_2 \le \lambda_3 \le \lambda_4 $ be the eigenvalues of this matrix. Since this is a Laplacian matrix, the smallest eigenvalue is $\lambda_1 = 0$. The second smallest eigenvalue of a Laplacian matrix is the algebraic connectivity of the graph.
Find determinants of matrices A=$\begin{bmatrix}a & 3 & 0 & 5\\0 & b & 0 & 2\\ 1 & 2 & c &3\\ 0&0&0&d \end{bmatrix}$ and B=$\begin{bmatrix}x & y& Stack Exchange Network Stack Exchange network consists of 183 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge
The determinant of b is adf. Notice that the determinant of a was just a and d. Now, you might see a pattern. In both cases we had 0's below the main diagonal, right? This was the main diagonal right here. And when we took the determinants of the matrix, the determinant just ended up being the product of the entries along the main diagonal.

A matrix is considered to be a singular matrix if its determinant equals 0. For example, a matrix x with zero members in the first column. The determinant in this example is 0, according to the principles and properties of determinants. As a result, matrix x is unquestionably a singular matrix. In nature, a singular matrix is non-convertible.

Instead, a better approach is to use the Gauss Elimination method to convert the original matrix into an upper triangular matrix. The determinant of a lower or an upper triangular matrix is simply the product of the diagonal elements. Here we show an example.
