MATLAB Programming

Calling Functions
The example above meets all three criteria and is therefore a function call
using command syntax:
ls ./d
The following examples are not function calls using command syntax:
% No white space following the ls identifier
% Interpretation: elementwise division
ls./d
% Parenthesis following white space
% Interpretation: function call using function syntax
ls ('./d')
% Assignment operator following white space
% Interpretation: assignment to a variable
ls =d
% Operator following white space, followed in turn by
% more white space and a variable
% Interpretation: elementwise division
ls ./ d
Passing Certain Argument Types
This section explains how to pass the following types of data in a function call:
• “Passing Strings” on page 4-61
• “Passing Filenames” on page 4-62
• “Passing Function Handles” on page 4-63
Passing Strings
When using the function syntax to pass a string literal to a function, you
must enclose the string in single quotes, ('string'). For example, to create a
new directory called myapptests, use
mkdir('myapptests')
