MATLAB Basics for Engineering Students

Study Notes

Starting MATLAB

Use the command matlab in the command line or terminal to start MATLAB.
Ensure that the MATLAB environment is correctly installed to avoid errors.

Creating MATLAB Variables

Variables can be created by simply assigning a value using the syntax variableName = value;.
Variable names must start with a letter and can include letters, numbers, and underscores.
MATLAB is case-sensitive, meaning Variable and variable are treated as distinct entities.

Plot Annotations in MATLAB

Use title('Your Title') to add a title to the plot.
Axis labels can be included with xlabel('X-axis Label') and ylabel('Y-axis Label').
Annotations or text can be added at specific points with the text(x, y, 'Your Text') command.

Entering Vectors in MATLAB

A vector can be created using square brackets, e.g., v = [1, 2, 3, 4]; for a row vector or v = [1; 2; 3; 4]; for a column vector.
Elements within the brackets are separated by spaces (for row vectors) or semicolons (for column vectors).

Generating Matrices in MATLAB

Create a matrix using square brackets with rows defined by semicolons, e.g., M = [1, 2, 3; 4, 5, 6; 7, 8, 9];.
MATLAB allows operations on matrices such as addition, multiplication, and transposition using built-in commands.
