Dr. Hari V S Department of Electronics and Communication College of Engineering Chengannur What You will Learn You will learn to create matrices You will learn to solve linear equations by computing the inverse of a matrix. You will learn to compute the eigen values of a matrix Matrices using Python A $5\times 3$ matrix is created, printed and displayed as an image using the code below. Its transpose is generated by the $transpose()$ function. from scipy import * from pylab import * x=mat([[1,2,3,4,5],[4,5,6,9,15],[7,8,9,23,25]]) print x print shape(x) print transpose(x) matshow(x) show() Solution of Linear Equations Linear systems are represented by matrix equations. See the electrical network in the figure below. All resistances are in $\Omega$. The network is described by the set of equations. \begin{equation} 9I_{1}-4 I_{2}=20 \end{equation} \begin{equation} -4I_{1}-6 I_{2}=-10 \end{equation} \begin{equation} 8I_{3}-3 I_{4}=-20 \end...
