I found a bug in function loading the GSHHS. Recently, the number of arguments in the header of polygon stored in GSHHS files have changed.

However, I had some trouble loading GSHHS files.
Looking inside the code, I found that the number of elements read in the header of each polygon did not match the GSHHS file.
It has changed from 8 to 11
ftp://ftp.soest.hawaii.edu/pwessel/gshhs/README.TXT

In file 'mu_coast.m' for function '[A,cnt] = get_gheader(fid)'
I had to change the line
[A,cnt]=fread(fid,8,'int32');
to
[A,cnt]=fread(fid,11,'int32'); where 11 is the new number of elements to read in the header.

Without this change, nothing was displayed.

The maintainer of this toolbox is aware of this bug , and will try to solve it.

Look at the / \ directory separators. A classic *n*x issue, or is this a typo in the post or somewhere in the code?

Thank you very much!
the change in mu_coast.m fixed the problem....
