numerical computations. But it is also a programming language‚ and the standard Scilab library contains around 2000 Scilab coded functions. The Scilab syntax is simple‚ and the use of matrices‚ which are the fundamental object of scientific calculus‚ is facilitated through specific functions and operators. These matrices can be of different types including real‚ complex‚ string‚ polynomial‚ and rational. Scilab programs are thus quite compact and most of the time are smaller than their equivalents in

Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

Chapter 4 DETERMINANTS All Mathematical truths are relative and conditional. — C.P. STEINMETZ 4.1 Introduction In the previous chapter‚ we have studied about matrices and algebra of matrices. We have also learnt that a system of algebraic equations can be expressed in the form of matrices. This means‚ a system of linear equations like a1 x + b1 y = c 1 a2 x + b2 y = c 2 ⎡ a b ⎤ ⎡ x ⎤ ⎡c ⎤ can be represented as ⎢ 1 1 ⎥ ⎢ ⎥ = ⎢ 1 ⎥ . Now‚ this ⎣ a2 b2 ⎦ ⎣ y ⎦ ⎣ c2 ⎦ system of equations

Matrix Elimination -This method can be used to solve systems of linear equations involving two or more variables. However‚ the system must be changed to an augmented matrix. -This method can also be used to find the inverse of a 2x2 matrix or larger matrices‚ 3x3‚ 4x4 etc. Note: The matrix must be a square matrix in order to find its inverse. An Augmented Matrix is used to solve a system of linear equations. a1 x + b1 y + c1 z = d1 a 2 x + b2 y + c 2 z = d 2 a3 x + b3 y + c3 z = d 3 System of Equations
