When i covert a structure to cell array, my fieldNames disappear

I am trying to convert a structure to a cell array, when i do that, i am not able to see field on my new cell array, i only see values. Is there a way to have both field and values on the cell array?

Answer 1

There is no meta data text info for cell array. Use struct2table() to convert structure to table.

Error using table.fromScalarStruct (line 480)
Fields in a scalar structure must have the same number of rows.

Error in struct2table (line 65)
        t = table.fromScalarStruct(s);

This is the error i have when i convert to table.

"Is there a way to have both field and values on the cell array?"

Let us create a sample structure

S.x = linspace(0,4*pi);
S.y = cos(S.x);

You can use fieldnames and struct2cell to extract the values:

name=fieldnames(S);
value=struct2cell(S);

Shambhavi, you can use fieldnames to extract the fieldnames from your structure and add it to the end of your new cell array. For example, taking this 1-by-2 structure array from the MATLAB documentation:

% sample structure
field1 = 'f1';  value1 = zeros(1,10);
field2 = 'f2';  value2 = {'a', 'b'};
field3 = 'f3';  value3 = {pi, pi.^2};
field4 = 'f4';  value4 = {'fourth'};
s = struct(field1,value1,field2,value2,field3,value3,field4,value4);

% write data from structure to cell array
sCell = struct2cell(s);
% add fieldnames to cell array
sCell(:,:,end+1) = fieldnames(s);

sCell(:,:,1) to sCell(:,:,end-1) now contain your data, while sCell(:,:,end) contains your fieldnames.

If you prefer to have the fieldnames listed first, in sCell(:,:,1), followed by your data in sCell(:,:,2) to sCell(:,:,end), issue the following command after the above:

sCell = circshift(sCell,1,3);
