Hello,

I am trying to run the attached code, but it fails at line 51

Input parameters:

>> obs(1) = struct('type','fixed','r',2,'phi',pi/4,'pulsePeriod',0.5,'n',400) ;
>> obs(2) = struct('type','free','r',1.5,'phi',pi/4,'pulsePeriod',0.5,'n',400) ;
>> run_Schwarzschild(obs,8,[0 2.5 0 2.5])
error: scalar cannot be indexed with .
error: called from
    run_Schwarzschild at line 51 column 10

Not sure how to solve this?

  Hi Lester,

my bet is: the o(k).Color (line 51) is the problem. o(k) is defined line 42. o(k).Color could be a Matlabism not supported in Octave? You may want to replace it w/ get(ok(k), 'color').

For example, in an Octave prompt, I can provoke this error, but also do get(.,'color'):

    HTH,
