Operasi Dasar Baris/Kolom Matriks Secara Interaktif Dengan Menggunakan R

The linear algebra applications available today usually only provide the result. So, it is a challenge to overcome this, and innovation needed in computing aspect. One of popular open-source programming languages ​​is R. computational R needs be explored further, explore logic. creation function environment with list involvement local global variables/objects has received little attention. Based on problems formulated, this study proposes two objectives, namely (1) developing an program that able interactive step-by-step solutions, obtain solution system equations, (2) R’s ability create handle variables. An created, starting creating environment. This filled four related functions, “exchange”, “multiply”, “fold”, “yield”. These functions are connected each other through object. Users can type perform row/column operations, interactively step by step. environmental program, named OBE. OBE accepts input form coupling matrix derived from equations. final result process chain given “result” function. will display matrices, Original Matrix which Equivalent Matrix.
