I'd like to use the substruct function to create a structure for use in subsref. The purpose is to index a string using subsref instead of the usual ( ) notation because I'm subscripting the output of a function. This is a simple example of what I'm trying to do (in my actual code, this is used within a cellfun, so the strings can be of different lengths and the replacement isn't always in the same place):
data = 'quick brown fox';
data2 = strrep(data, 'brown', 'green');
data2(7:end)
Heres where I tried to define this subscripting with substruct:
data = 'quick brown fox';
S = substruct('()', {[7:end]});
subsref(strrep(data, 'brown', 'green'), S)
but this just gives me an error:
Error using substruct (line 30)
SUBSTRUCT takes at least two arguments.
Error in myfile (line 3)
S = substruct('()', {(7:end)});
I've been over and over the documentation for both substruct and subsref, and no where do they mention end. How do I do this?
