using command gf or map to other key for matlab function

[frank wang]

Hi,

I am a lot of matlab function files. the function name is the same as
file name without the file extension .m. In the Vim, if I use command
gf trying to find the file under the cursor, it could not find it
since it missed the extension .m. Could someone help me to create a
map to solve this problem?

Thanks

Frank
