MATLAB® operates primarily on arrays and matrices, both in whole and in part. A matrix is a two-dimensional array often used for linear algebra.
Variables in MATLAB are typically arrays that can hold many numbers. When you want to access selected elements of an array, use indexing.
The workspace contains variables that you create within or import into MATLAB from data files or other programs.
When you are working with text, enclose sequences of characters in single quotes.
MATLAB provides a large number of functions that perform computational tasks. To call a function, enclose its input arguments in parentheses.
Graphics functions include 2-D and 3-D plotting functions to visualize data and communicate results.
The simplest type of MATLAB program is called a script. A script contains a sequence of commands and function calls.
All functions have supporting documentation that includes examples and describes the function inputs, outputs, and calling syntax.
