axesm

Hi, im trying to write an m-file that uses an axesm function. I am imaginging the sky in radiowaves and cannot get the function to work. It runs but errors when the graph show. Can anyone help? Thanks Luke axesm('hammer'); patchm (lat, long, 'f'); setm (gca,'Origin', [30 130 135]);

Please expand upon what error you encounter.

Please insert a copy of the error message in this question and use the code formatting.

@Luke, please help us to help you! It would be easier to diagnose the problem if you provide some data for lat and long and tell us what the error message is.

[Luke]

its not displaying an error anymore. Just running and loading the graph my code is now,

f=d-v;

r = srtdata1.ra;

dec = srtdata1.dec;

axesm('hammer','Grid','on','Frame','on');

patchm (lat, long, 'f');

setm (gca,'Origin', [30 130 ]);

I know im being a pain but im not used to using matlab, Thanks guys

[Andrew Newell]

O.k., that's a start. Now what are the values of d, v, and srtdata1?

[Luke]

d is the time, v is a polyval and srtdata1 is just the raw data

[Andrew Newell]

Can you give me some actual numerical values for these data? Then tell me what you see when you run your code and what you want to see.

[Luke]

there matrices and channels. Its data from the galactic plane so theres a lot of it. Thanks again.

I'm not sure what your goal is, but the errors in the above code go away if you provide values for lat and long:

axesm('hammer'); 
lat = 0; long = 0;
patchm (lat, long, 'f'); 
setm (gca,'Origin', [30 130 135]);

[Luke]

No sorry, I had arragned a similar code that gave the same disply but the problem axes to be because i have values to use

[Luke]

for lat and long

[Andrew Newell]

I don't understand what you are saying. Can you try editing the original question?

[Luke]

Im trying to write an axesm function that will show the galactic plane. so far i bieleve that i have the basic script for it working but i am having problems setting the axes. i need then to be the right assention and declination for each corresponding data point we have observed. data that i already have?

I hope that clears it up for you

thanks
