{'y = sin(x)' }
The cell array does not include field names. To return the field names in a cell array, use the fieldnames
function. fieldnames
and struct2cell
return the field names and the values in the same order.
fields = fieldnames(S)
fields = 3×1 cell
{'x' }
{'y' }
{'title'}
Input Arguments
Input structure array. S
can be a structure array of any size. If
S
is an m
-by-n
structure
array with p
fields, then C
is a
p
-by-m
-by-n
cell
array.
Extended Capabilities
Usage notes and limitations:
If
S
is a variable-size array of structures, then each field of every element must have the same type. Heterogeneous cell arrays cannot be variable-size.For a fixed-size array of structures
S
, ifstruct2cell
cannot convertS
to a homogeneous cell array, then the output cell array is heterogeneous. A heterogeneous output cell array can have a maximum of 1024 elements.
This function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.
This function fully supports distributed arrays. For more information, see Run MATLAB Functions with Distributed Arrays (Parallel Computing Toolbox).
