Structure outline

Prints the hierarchy outline of a structure with optionally, field values.

Description

This function prints the hierarchical outline of a structure to the command window or a file. Optionally, field values can be printed as well.

Worked for me.

[Matt Brunner]

Awesome! Exactly what I was looking for. Thank you.

[Joseph]

This is really great. Good job.

very useful

[Juergen Kurzmann]

This is a really helpful function for getting a concise overview of data structures (struct) as well as for their documentation!

[B. Roossien]

I've fixed a number of bugs and added some improvements following feedback from Holger Krause and Juergen Kurzmann. The new file should be available in 2-3 days.

thank you very much really helpful function

I'm using this function to print out nicely formatted log files containing parameters of various types. strucdisp is just the right tool for this job.

There are three smaller issues:

1. It would be nice, to handle logicals separately (output as text 'true' or 'false' at least for single values).

2. The line for numeric vectors is missing a space in front of the opening bracket.

3. In some cases empty fields get duplicated and occur one time as an empty string '' and a second time as an empty double array [ ].

[B. Roossien]

This function has been updated. Some bugs were fixed. Its performance is enhanced and new functionalities (printing small matrices and handling structure arrays) have been added.

Problem resolved. My new rating is now the correct one.

This will be a useful utility for those of us who sometimes generate complicated structures.

I do like this utility, but there is a significant bug. The help states that all arguments but the first are optional. I tried passing in the third argument, but not the second, supplying an empty argument to the second as a placeholder. This should be acceptable. Its also the standard way that Matlab tools use to allow some arguments to be defaulted.

strucdisp(s,[])
??? Operands to the || and && operators must be convertible to logical scalar values.

Error in ==> strucdisp>get_fields at 151
if (depth < 0) || (indent + 1 < depth)

Error in ==> strucdisp at 64
liststr = get_fields(structure, 0, depth, flag_value, max_length);

Arguments that take on a default value should test for empty values provided using isempty, and if empty, then provide the default.

I'd have rated this a 5 otherwise, and I will happily raise my rating to that level if it is repaired.
