Re: Getting Matlab geophysics code running in Octave

[Lester Anderson]

Hi Juan,

I moved a copy of defval.m into the same folder as the two main files (coheref2.m and forsyth.m), I fixed the references to values that were not declared in forsyth.m, and it got a little farther along -

octave:9> coheref2
ans = [](0x0)  ---------> these look odd!
ans = [](0x0)
ans = [](0x0)
ans = [](0x0)
ans = [](0x0)
ans = [](0x0)
error: 'xver' undefined near line 63 column 6
error: called from:
error:   c:\matlab\functions\simmons_matlab\forsyth.m at line 63, column 3    ------->        if xver==1
error:   c:\matlab\functions\simmons_matlab\coheref2.m at line 33, column 2    ------->   C=forsyth(Te,lambda,f2,r);
octave:9>

Lines 62-65 forsyth.m

  xver=0
  if xver==1
    disp(sprintf('E= %5.3g; v= %5.3f',E,v))
  end

The working directory now has all three files in place - I cannot see what else could be missing. I have attached the updated forsyth.m

Changes made :   defval('g',9.81);
  G=6.67e-11;

It is looking more like the issue is in forsyth.m ?

All rather confusing

and can you locate defval? In which folder it is placed?

forsyth.m
