(for tangent), log (for natural logarithm, ln), exp (for exponential function, ex), and atan (for arctangent) as well as more specialized mathematical functions. MATLAB also has several built-in constants, including pi (the number π), i (the complex number i = √−1), and Inf ( ). >> log(exp(2)) ans = 2 >> log10(100) ans = 2 >> sin(pi) ans =
MATLAB a natural choice for numerical computations. The purpose of this tutorial is to familiarize the beginner to MATLAB, by introducing the basic features and commands of the program.
In this introduction we will describe how MATLAB handles simple numerical expressions and mathematical formulas. The name MATLAB stands for MATrix LABoratory.
Y = log(X) returns the natural logarithm ln(x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally.

Boolean algebra can be done in MATLAB using the logical operators AND (&) , OR (j) and NOT (˘). For example given an arbitrary boolean variable S: >> S | ~S ans = 1 Note: MATLAB implicitly "casts" data types to avoid syntax errors: Logical values are converted to 1 and 0 when used as numbers. >> (2 < 3) * 3 ans = 3 >> true * 3 ans = 3
