hi all, I'm using OCTAVE 3.0.2 under windows XP and want to install sundials 2.3.0 into it. Now I have done installation and got the MEX files, however, it gave such error when I used it: error: library initialization routine failed: d:\octave\3.0.2_gcc-4.3.0\sundials \sundialsTB\cvodes\cvm\cvm.mex error: failed to install .mex file function `cvm' error: `cvm' undefined near line 39 column 1 ... I tested other codes as well.I find that if the file is OCT then OCTAVE can run it while if it produces *.mex file then OCTAVE considers it as an undefined m file. Any one could help me? Many thanks,
