Problem 86. Renaming a field in a structure array

Created by Cody Team

Solve Later

MATLAB has a setfield and a rmfield, but not a "rename field". You need to write one for this problem.

Example

Suppose

 s(1).foo = 1;
 s(1).bar = 'one';
 s(2).foo = 2;
 s(2).bar = 'two';

and you want the field "bar" to be renamed "baz". Given the inputs s, oldField, and newField, you must return this output structure with all the data still in place.

 s(1).foo = 1;
 s(1).baz = 'one';
 s(2).foo = 2;
 s(2).baz = 'two';

Does "All the data still" mean, that the fields are not re-ordered? A lot of the solutions change the order of the fields.

Currently, Matlab has the function renameStructField.

When I run the test suite on my computer, this solution works. It passes the test suite.

This fails, if the fieldname to be replaced appears as part of another fieldname. Example: S.ab=1; S.a=2; renamefield(S, 'a', 'c')
