Function Input Arguments
When parentheses follow a function name in a function declaration or call, the
enclosed list contains input arguments used by the function:
function sendmail(to, subject, message, attachments)
Percent — %
The percent sign is most commonly used to indicate nonexecutable text within
the body of a program. This text is normally used to include comments in your
code. Some functions also interpret the percent sign as a conversion specifier.
See “Help Text” on page 4-12 for more information.
Single Line Comments
Precede any one-line comments in your code with a percent sign. MATLAB
does not execute anything that follows a percent sign (that is, unless the
sign is quoted, '%'):
% The purpose of this routine is to compute
% the value of ...
Conversion Specifiers
Some functions, like sscanf and sprintf, precede conversion specifiers with
the percent sign:
sprintf('%s = %d', name, value)
Percent-Brace — %{ %}
The %{ and %} symbols enclose a block of comments that extend beyond one
line.
Block Comments
Enclose any multiline comments with percent followed by an opening or
closing brace.
%{
