A complex number has an imaginary component and is of the form a + bi. (And i is the square root of -1 in this application.)
A matrix is a table of numbers. For example, we might give the current (x,y,z) coordinates of a dozen asteroids using a 12 * 3 matrix.
A complex matrix is a matrix of complex numbers.
They are elements of of a set which may consist of integers, real or complex numbers, polynomial expressions, matrices.
The Pauli matrices are a set of three 2x2 complex matrices commonly used in quantum mechanics, represented as ( \sigma_x ), ( \sigma_y ), and ( \sigma_z ). The eigenvalues of all three Pauli matrices are ±1. Specifically, ( \sigma_x ) has eigenvalues 1 and -1, ( \sigma_y ) also has eigenvalues 1 and -1, and ( \sigma_z ) likewise has eigenvalues 1 and -1. Each matrix's eigenvectors correspond to the states of a quantum system along different axes of the Bloch sphere.
The matrices must have the same dimensions.
Only square matrices have a determinant
There are no matrices in the question!
I suggest asking separate questions for complex numbers, and for matrices. Complex numbers are used in a variety of fields, one of them is electrical engineering. As soon as AC circuits are analyzed, it turns out that complex numbers are the natural way to do this.

They are elements of of a set which may consist of integers, real or complex numbers, polynomial expressions, matrices.
Only square matrices have inverses.

Matrices are used in electrical circuits primarily for analyzing complex networks through techniques such as nodal and mesh analysis. By representing circuit components and their relationships as matrices, engineers can systematically solve for currents and voltages using linear algebra methods. This approach simplifies calculations, especially in circuits with multiple elements, allowing for easier manipulation and understanding of circuit behavior. Additionally, matrices can facilitate the use of simulation software for circuit design and analysis.
how is matrices is applicable in our life?

The singular form of matrices is matrix.
There are no matrices in the question!
In mathematics matrices are made up of arrays of elements.
