I have a structure with one field. I try to remove specific elements using i.e.:
trial(5).Hs_m = []
but the element remains in the structure, just having a value of "[]". Is there a way to remove it?

There is a specific function to remove a field from a structure: rmfield
Here is an example:
S.field1 = 'hello';
S.field2 = 456;
S
S =
struct with fields:
field1: 'hello'
field2: 456
Now remove one field:
S = rmfield(S,'field1')
S =
struct with fields:
field2: 456

So, why mentioning the field? In this case just remove the structure entry. Following your example, you can remove the 5-th entry with
trial(5) = []
regardless of the field(s).
