comments

Description

A sequence of two consecutive slashes // out of a string definition marks the beginning of a comment. The slashes as well as all the following characters up to the end of the lines are not interpreted.

Another way to comment a block of code is to use /* at the beginning and */ at the end. It is more useful than // which must be positioned at the beginning of each line to comment.

Inside a function, the first comment lines, up to the first instruction or an empty line may be used to provide the default contents for the function help.

Examples

g=9.81// the gravity

text='a//b'

/* As this comment is quite long to be on many lines,
the symbols slash and star to start the comment
and star and slash to end the comment are used */

function y=myfunction(x)
  // myfunction computes y=x^2+1
  // x should be a vector or matrix
  y=x^2+1
endfunction

help myfunction
