MATLAB Programming

3 Basic Program Components
Cell Array Indexing
Index to a specific cell array element by enclosing all indices in curly braces:
A = C{4,7,2}
See “Cell Arrays” on page 2-94 for more information.
Dot — .
The single dot operator has the following different uses in MATLAB.
Structure Field Definition
Add fields to a MATLAB structure by following the structure name with a
dot and then a field name:
funds(5,2).bondtype = 'Corporate';
See “Structures” on page 2-75 for more information.
Object Method Specifier
Specify the properties of an instance of a MATLAB class using the object
name followed by a dot, and then the property name:
val = asset.current_value
See “MATLAB Classes” on page 2-118 for more information.
Dot-Dot — ..
Two dots in sequence refer to the parent of the current directory.
Parent Directory
Specify the directory immediately above your current directory using two
dots. For example, to go up two levels in the directory tree and down into the
testdir directory, use
cd ..\..\testdir
