Converting Struct field to array

I have an n-value structure array with multiple fields, and want to extract a specific field (all values thereof are (1x4) single arrays) into a nx4 array.

MyMatrix = [MyStruct(:).FieldC];

concatenates the values of the field, giving me a 1x(n*4) array. There's probably a way to reshape that, but I would appreicate a more direct solution as I'm doing this in the command window on an as-needed basis, rather than via a script.

Does this do what you want?

MyMatrix = vertcat(MyStruct.Field);

It does indeed. Thanks!

This does not work if the field is 2 or more structure layers down from the indexing. e.g. d.field1.field2 where d is a structure array, e.g. d(1).field1.field2

@Babak: correct. I explain the reason why here:

MyMatrix=cell2mat(struct2cell(MyStruct));

Editing my original post to the following effect: there are multiple field in the structure array, and I'm only looking to extract 1 of them to an array.

David Hill's solution worked for me, the other one did not. My context was a struct with just one field level.
