[Harvey J Stein]

Package: caja
Version: 1.12.7-1+rosa
Severity: normal

Dear Maintainer,

Caja is listing some octave (.m) files as type Objective-C source code.  For
example, the following file (hw06reduced.m) is listed as Objective0C source
code:

1;


times = [0, 1, 2, 1000];
lambdas = [0.015, 0.02, 0.025, 0.025];

% Step function for defining hazard rate
function s = step(x, y, t)
   i = find(x>t, 1);
   if isempty(i)
       s = y(end);
   elseif i == 1
      s = [];
   else
      s = y(i-1);
   end;
end;

% Survival probabilities
function s = survival(times, lambdas, t)
    dt = diff(times);
    intlambdavect = [0 cumsum(dt .* lambdas(1:end-1))];
    c = interp1(times, intlambdavect, t);

    s = exp(-c);
end;

% Spot spreads as a function of hazard rates
function s = spread(times, lambdas, R, t)
    invtimes = -1 ./ t;
    s = invtimes .* log(1 - (1-R)*(1-survival(times, lambdas, t)))*10000;
end;
