Undefined function or method 'quad8' for input arguments of type 'char'.

Having above error in Matlab 7 but no issue in matlab 6.5. Please assist.

Advance Thanking

What are you expecting quad8 to be? It doesn't appesar to be in any builtin toolbox, at least certainly not one that my Matlab 2016a is suggesting.

sample code

   exptecquad_1(tiki,1)=quad8('quadexptec','','',''......)

[Walter Roberson]

quad8 is long obsolete...

http://cens.ioc.ee/local/man/matlab/techdoc/ref/quad.html

quad8 implements a higher order method using an adaptive recursive Newton-Cotes 8 panel rule

It was replaced with quadl starting in MATLAB 6.0

Thank you . Hope is the same in matlab 7.
