Q: Double integration in Matlab 5.0
Posted:
Jul 15, 1997 11:30 AM


I was using the suggestion in Technical notes 1502 (dblquad.m and innerlp.m) to perform a double integration. The method works in Matlab 4.2 But in Matlab 5.0, I got the following error message:
??? Undefined function or variable 'QUAD_RECURSION_COUNT'.
Error in ==> /software/matlab50/toolbox/matlab/funfun/quad.m On line 79 ==> if ~isempty(QUAD_RECURSION_COUNT) & (QUAD_RECURSION_COUNT > 1)
Errorr in ==> dblquad.m On line 14 ==> Q = quad('innerlp', outmin, outmax, tol, trace, intfcn, ...
Any ways to get around this problem please ? Thanks....
Yours, Tony Chan wcchan@wam.umd.edu
