Delay here too; new work station to set up. If MS put in any more helps, the thing wouldn't work at all.
----- Original Message ----- From: Søren Hauberg To: dmelliott Cc: [email protected] Sent: Sunday, June 07, 2009 4:51 AM Subject: Re: [OctDev] Developer Registration Request Hi Sorry 'bout the delay in reply... 1) The package you sent contains three files: the actual function, a demo function, and some documentation. This is two files too many. The documentation should be integrated with the help text of 'integ1es'. The demo should be made part of the 'integ1es.m' file. Specifically, this file should contain something like %!demo %! ord = XXX: pick a good example value %! for pts = [2:45,100,200,500,1000,10000]; %! if (pts == 1) %! f = ((xu+xl)*0.5)^ord; %! else %! f = linspace(xl,xu,pts).^ord; %! endif %! %! I = integ1es(f,xl,xu); %! %! E = I*(ord+1)/(xu^(ord+1)-xl^(ord+1))-1; %! %! printf("Points = %5.0d I = %7.5f RelErr = %10.3g \n",pts,I,E); %! %! endfor at the end. This example will then be available when the user types 'demo integ1es'. These two changes should be made to avoid filling up the namespace. Could you make these changes? 2) Carlo, where should this function go. Is the 'integration' package a suitable place? 3) If you put these functions in the public domain then you should not include the GPL text as part of the license. You have previously said that you would like to publish this as public domain. If this still stands, then please only have the following license: ## This file is in the public domain. ## It would be appreciated if the statement of authorship is ## preserved. Please put this text _after_ the help text as otherwise it seems 'help integ1es' doesn't work.
