As well as indexing a structure with ".", Octave can create a structure
with the struct
command. struct
takes pairs of arguments,
where the first argument in the pair is the fieldname to include in the
structure and the second is a scalar or cell array, representing the
values to include in the structure or structure array. For example
struct ("field1", 1, "field2", 2) => ans = { field1 = 1 field2 = 2 }
If the values passed to struct
are a mix of scalar and cell
arrays, then the scalar arguments are expanded to create a
structure array with a consistent dimension. For example
struct ("field1", {1, "one"}, "field2", {2, "two"}, "field3", 3) => ans = { field1 = (, [1] = 1 [2] = one ,) field2 = (, [1] = 2 [2] = two ,) field3 = (, [1] = 3 [2] = 3 ,) }
Create a structure and initialize its value.
If the values are cell arrays, create a structure array and initialize its values. The dimensions of each cell array of values must match. Singleton cells and non-cell values are repeated so that they fill the entire array. If the cells are empty, create an empty structure array with the specified field names.
Additional functions that can manipulate the fields of a structure are listed below.
Remove field f from the structure s. If f is a cell array of character strings or a character array, remove the named fields.

Set field members in a structure.
oo(1,1).f0= 1; oo = setfield(oo,{1,2},'fd',{3},'b', 6); oo(1,2).fd(3).b == 6 => ans = 1Note that this function could be written
i1= {1,2}; i2= 'fd'; i3= {3}; i4= 'b'; oo( i1{:} ).( i2 )( i3{:} ).( i4 ) == 6;See also: getfield, rmfield, isfield, isstruct, fieldnames, struct.
Return a struct with fields arranged alphabetically or as specified by s2 and a corresponding permutation vector.
Given one struct, arrange field names in s1 alphabetically.
Given two structs, arrange field names in s1 as they appear in s2. The second argument may also specify the order in a permutation vector or a cell array of strings.
