m_proj question: unexpected error

I have vector of lat and lon defined as:

lat = linspace(90,32,30);
lon = linspace(0,358,180);

I then do m_proj:

m_proj('equidistant,'lon',[lon(1) lon(end)],'lat',[lat(1),lat(end)]);

Then:

[x,y]=mll2xy(lon,lat);

This gives me an error of "inputs must have the same size". Any suggestions? I think I used this function before with success. Thank you!

The clue's in the name- one is a 1x30 vector, the other's 1x180; you can make them the same size by setting the 3rd argument in linspace the same for both lat and lon.

My guess is that you want

[Lat, Lon] = ndgrid(lat, lon);
[x,y] = mll2xy(Lon,Lat);

Hi, well actually that is what is giving to me. I cannot change it. I did [x,y]=m_ll2xy(lon,lat,'clip','off')
