Thread Subject: quad2d sfit

Hi All,

I am looking to integrate the area under a surface fit. I searched for a method to do this and found a page on qyad2d
http://www.mathworks.com/access/helpdesk/help/toolbox/curvefit/index.html?/access/helpdesk/help/toolbox/curvefit/quad2d.html

which claimed the function quad2d will "Numerically integrate sfit object"

However when I try to run it I get the error message

"First input argument must be a function handle."

Can anyone explain to me why this is happening, do I need a more recent version of Matlab?

Thanks,
A

Did you read my explanation in the thread in which you posted this message
yesterday?

If so, and you did not feel it answered your question, respond in that
thread indicating what you feel it did not answer.
