CHAPTER 4
COURSE’S MAIN TOPICS
4.1 Vectors and Matrices:
Vectors and matrices are fundamental components of MATLAB, forming the backbone of its matrix-based
computing paradigm. In MATLAB, a vector is a one-dimensional array that can contain numerical data, and
it can be created using square brackets. For example, v = [1, 2, 3, 4, 5] creates a vector named v with five
elements. Matrices, on the other hand, are two-dimensional arrays that extend the concept of vectors to
multiple dimensions. A matrix can be created using semicolons to separate rows, like A = [1, 2, 3; 4, 5, 6; 7,
8, 9], defining a 3x3 matrix named A.
Vectors and matrices facilitate efficient mathematical operations in MATLAB. Basic arithmetic operations can
be performed element-wise or using matrix operations. For instance, C = A + B adds corresponding elements
of matrices A and B, while D = A * B performs matrix multiplication if the dimensions are appropriate.
MATLAB provides convenient indexing and slicing mechanisms for accessing specific elements or subsets of
vectors and matrices, enhancing the flexibility of data manipulation.
MATLAB's built-in functions and operators are designed to seamlessly handle vectors and matrices, allowing
for streamlined coding in numerical and scientific applications. Whether solving linear algebraic equations,
implementing signal processing algorithms, or conducting statistical analyses, the use of vectors and matrices
in MATLAB contributes to concise and efficient programming practices. Overall, the elegant handling of
vectors and matrices makes MATLAB a powerful tool for mathematical and computational tasks in various
scientific and engineering disciplines.

4.2 Array Calculations:
Array calculations in MATLAB form the backbone of its computational power, allowing users to perform
intricate mathematical operations and manipulations on arrays of data. Arrays, whether vectors or matrices,
can be used to represent and process vast datasets efficiently. In MATLAB, array operations can range from
basic arithmetic to advance linear algebraic computations. The ability to perform element-wise operations
simplifies complex calculations, enabling concise and expressive code.
Element-wise operations involve performing a specific operation on each corresponding pair of elements in
arrays. For example, given arraysAand B, the command C =A+ B adds each element ofAto its corresponding
element in B, producing a new array C. Similarly, subtraction, multiplication, and division can be executed
element-wise. This mechanism allows for streamlined coding and is a hallmark of MATLAB's simplicity and
power in handling arrays.
Beyond element-wise operations, MATLAB supports matrix operations, including matrix multiplication,
inversion, and eigenvalue calculations. These operations are crucial for tasks such as solving systems of linear
equations, signal processing, and statistical analyses. For instance, the * operator performs matrix
multiplication when used with arrays, facilitating concise and efficient code for linear algebraic tasks.
Indexing and slicing further enhance array manipulations. MATLAB allows users to access specific elements
or subsets of arrays using indices. This feature is particularly valuable when working with large datasets,
enabling the extraction of relevant information or the modification of specific elements.
The MATLAB environment also supports broadcasting, a mechanism that automatically expands smaller
arrays to match the size of larger arrays in certain operations. This enhances code readability and reduces the
need for explicit expansion operations.

promote code readability. To call a function, its name is followed by parentheses, and any required input
arguments are placed within these parentheses. Output arguments, if any, are specified on the left side of the
assignment statement.
1. Basic Syntax: The general syntax for calling a function is output = functionName(input1, input2,
...), where function Name is the name of the function, and input1, input2, etc., are the input
arguments.
2. Built-In Functions: MATLAB includes a vast array of built-in functions that cover mathematical
operations, signal processing, data analysis, and more. Examples include sin, cos, mean, and max.
3. User-Defined Functions: Users can create their own functions using the function keyword. A user-
defined function typically resides in a separate file with a .m extension. The function name must match
the filename.
4. Input Arguments: Input arguments are values passed to the function for processing. They are
specified within the function call and can be variables, arrays, or constants.
5. Output Arguments: Functions can return one or more values as output. These output values are
assigned to variables on the left side of the function call.
6. Anonymous Functions: MATLAB supports the creation of anonymous functions using the
@(input) expression syntax. These functions are useful for short-term use in functions like integral
or fsolve.
7. Function Handles: Function handles are variables that store references to functions. They provide a
convenient way to pass functions as arguments to other functions or store them in data structures.
8. Variable Number of Inputs/Outputs: MATLAB functions can handle variable numbers of inputs
using the arraign syntax and variable numbers of outputs using the varargout syntax.
9. Nested Functions: Functions can be nested within other functions in MATLAB. These nested
functions have access to the variables of the enclosing function, allowing for more modular and
organized code.
10. Error Handling: MATLAB functions can incorporate error handling using constructs like try,
catch, and error. These mechanisms enhance the robustness of code by allowing graceful handling
of unexpected situations.
