SISTEM ALJABAR LINEAR DAN MATRIKS
Aljabar linear adalah bidang studi matematika yang mempelajari sistem persamaan linear dan solusinya, vektor, serta transformasi linear. Matriks dan operasinya juga merupakan hal yang berkaitan erat dengan bidang aljabar linear
Mengapa Matriks?Aljabar Linear lebih mudah di selesaikan dengan
MatriksKarakterisasi atau Pemodelan suatu sistem
Contoh AplikasiMenggambarkan Matriks
Penjualan 3 macam produk (I, II, dan III) di toko pada hari kerja (senin, selasa, rabu, kamis dst)
Contoh Aplikasi (a) Nodal Incidence Matrix. The network in Fig. 1
consists of six branches (connections) and four nodes (points where two or more branches come together). One node is the reference node (grounded node, whose voltage is zero). We number the other nodes and number and direct the branches. This we do arbitrarily. The network can now be described by a matrix A= [ajk], where
A is called the nodal incidence matrix of the network Show that for the network in Fig. 155 the matrix A has the given form.
Contoh Aplikasi
Fig I
karakterisasi koneksi dalam jaringan listrik, jaringan jalan penghubung kota-kota, proses produksi dan lain-lain
Operasi Penjumlahan dan Pengurangan MatriksJika A dan B adalah matriks yang
mempunyai ordo samaPenjumlahan dan Pengurangan dari A + B
adalah matriks hasil dari penjumlahan elemen A dan B yang seletak
Matriks yang mempunyai ordo berbeda tidak dapat dijumlahkan atau dikurangkan◦a.) A + B = B + A ◦b.) A + ( B + C ) = ( A + B ) + C ◦c.) k ( A + B ) = kA + kB = ( A + B ) k , k =

Derivation from the circuit in Fig. 159 (Optional). This is the system for the unknown currents x1 = i1, x2 = i2 x1 = i1 , x3 = i3 , in the electrical network in Fig. II. To obtain it, we label the currents as shown, choosing directions arbitrarily; if a current will come out negative, this will simply mean that the current flows against the direction of our arrow. The current entering each battery will be the same as the current leaving it. The equations for the currents result from Kirchhoff’s laws:
Kirchhoff’s Current Law (KCL). At any point of a circuit, the sum of the inflowing currents equals the sumof the outflowing currents.
Kirchhoff’s Voltage Law (KVL). In any closed loop, the sum of all voltage drops equals the impressed electromotive force.
Node P gives the first equation, node Q the second, the right loop the third, and the left loop the fourth, as indicated in the figure.
