Input examples of m_map toolbox but image is not clear

m_proj('lambert','lon',[-10 20],'lat',[33 48]); 

[CS,CH]=m_etopo2('contourf',[-5000:500:0 250:250:3000],'edgecolor','none');
 m_grid('linestyle','none','tickdir','out','linewidth',3);

colormap([ m_colmap('blues',80); m_colmap('gland',48)]);
brighten(.5);

ax=m_contfbar(1,[.5 .8],CS,CH);
title(ax,{'Level/m',''}); % Move up by inserting a blank line

Unrecognized function or variable 'm_proj'.

Input the code in Matlab and the picture is serrate.

But the example in https://www.eoas.ubc.ca/~rich/map.html#7._Lambert_Conformal_Projection_with_Med is

If someone have any ideas to look at. Thank You!

Hi @Yingnan Liu,

I was able to reproduce the issue you mentioned after installing the m_map toolbox. This might be due to the m_etopo2 function using a default dataset as indicated by this warning i encountered:

Warning: Cannot open /ocean/rich/more/mmapbase/etopo1/etopo2 !! \n Have you installed the Etopo2

database correctly?\n This (optional) database must be installed separately - see the M_Map user's

guide for instructions\n ----Using default elevation database instead

> In m_etopo2 (line 94)

In EEB551_LAB2 (line 2)

You can try installing the Etopo2 database to see if it resolves the low resolution image.
