Compiler Directives

2-9

Use the /%...%/ construct to delimit comments within your code. Use the %%

construct for line-based comments; all characters from

%% to the end of the line

become a comment.

Nondirective lines, that is, lines that do not have

% as their first nonblank

character, are copied into the output buffer verbatim. For example,

/* Initialize sysNumber */

int sysNumber = 3;

copies both lines to the output buffer.

To include comments on lines that do not begin with the

% character, you can

use the

/%...%/ or %% comment directives. In these cases, the comments are not

copied to the output buffer.

Note: If a nondirective line appears within a function, it is not copied to the

output buffer unless the function is an output function or you specifically

select an output file using the

%selectfile directive. For more information

about functions, see the “Target Language Functions” section in this chapter.

Line Continuation

You can use the C language \ character or the MATLAB sequence ... to

continue a line. If a directive is too long to fit conveniently on one line, this

allows you to split up the directive on to multiple lines. For example

%roll sigIdx = RollRegions, lcv = RollThreshold, block,\

"Roller", rollVars

%roll sigIdx = RollRegions, lcv = RollThreshold, block,...

"Roller", rollVars

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 281 282
