Formating all values of a structure field

4 views (last 30 days)
Is there a syntax for applying a format to all vlues of a given field in a structure array(without a loop)? E.g. I have a structure array with multiple fields, and 1 field has values which are all Datetimes. While I can format individual value.field pairs, I have not stumbled onto a syntax for applying that formatting to all values in that field without looping though the structure.
MyStruct(N).DateTimeField.Format = %preferred format
works, but my attempted expansions throw faults:
MyStruct.DateTimeField.Format = %preferred format
Fault: "Scalar structure required for this assingment"
MyStruct(:).DateTimeField.Format = %preferred format
Fault: "Expected one output from a curly braces or dot indexing expression, but there were [number of Values] results."

No, you cannot access nested fields of a struct array in Matlab directly. You need a loop.
