>> R = worldfilen​ame(getwor​ldfilename​(filename)​, 'geographic', size(RGB));

Getting Error : Index in position 1 exceeds array bounds (must not exceed 1). 

code: >> R = worldfilename(getworldfilename(filename), 'geographic', size(RGB));

>> size (worldfilename)

= 1 10

How can reduce my worldfilename which is a jgw file. or Can I increase array bounds?

My goal is to create a geoshow of Oxnard,CA with RGB = imread(filename) & R = worldfilename(getworldfilename(filename), 'geographic', size(RGB));

I suspect you might want worldfileread() instead of worldfilename in the outer level.

[Dominic Eslamian]

yes sorry worldfileread is correct. still get same error : /

[Walter Roberson]

What shows up for

which worldfilename
which getworldfilename
which size

Also please post your revised line of code so we are sure we are talking about the same thing.

Also break the line into parts on the command line, like testing

getworldfilename(filename)

so that you can isolate which variable it is complaining about.
