Values within a cell array must be numeric, logical, or char?

Don't seem to know what's wrong. I've tried everything I know. Here's the snippet containing the code:

    Fg = varargin{1};
  Ug = varargin{2};
  eps = varargin{3};
  sig = varargin{4};
  elems = varargin{5};
  L = varargin{6};
  A = varargin{7};
  E = varargin{8};

PPM={};
for i=1:3
    out1=num2cell(i);
    out2={num2cell(elems(1,1)) num2cell(elems(1,2))};
    out3=num2cell(L(i,1));
    out4=num2cell(A(i,1));
    out5=num2cell(E(i,1));
    PPM{i}={out1 out2 out3 out4 out5};

end
out={PPM}
set(handles.uitable1,'Data',out);
% Choose default command line output for postprocess
handles.output = hObject;

Looking backwards,

out={PPM}

so out is a 1 x 1 cell array whose first and only element is the array PPM

PPM{i}={out1 out2 out3 out4 out5}

so PPM is a 1 x 3 cell array, and each cell in PPM is to contain a 1 x 5 cell array

    out1=num2cell(i);
    out2={num2cell(elems(1,1)) num2cell(elems(1,2))};
    out3=num2cell(L(i,1));
    out4=num2cell(A(i,1));
    out5=num2cell(E(i,1));

the first, third, fourth, and fifth of which are to be cell arrays containing scalars, and the second of which is to be a 1 x 2 cell array inside of each of which is a cell array containing a scalar

If I analyze correctly, out is

{{{{scalar} {{scalar} {scalar}} {scalar} {scalar} {scalar}} {{{scalar} {{scalar} {scalar}} {scalar} {scalar} {scalar}} {{{scalar} {{scalar} {scalar}} {scalar} {scalar} {scalar}}}}

This is not something that can be represented in a uitable.

The data property for a uitable can be:

• a numeric array
• a logical array
• a character vector
• a cell array, each entry of which is a numeric scalar, a logical scalar, or a character vector

It is never possible to for the data property to have a cell inside a cell.

You have a particular problem with out2: in uitable, it is not possible for a single column to store multiple values (except in that character vectors are, in one sense, multiple values).

I think you need to go for 6 columns.

It looks to me as if you could construct a simple numeric output.

I notice that your out2 does not subscript with i. In the below I presume that was a mistake, that you want different outputs for the out2

idx = 1 : 3;
PPM = [idx.', elems(idx,1:2), L(idx,1), A(idx,1), E(idx,1)];

set(handles.uitable1,'Data', PPM);

This code replaces all of the looping and all of the {} construction. All of your data appears to be numeric so there is no need to break it up into individual cells. (I cannot actually tell that for sure, though: it is not impossible that some of your data is character vector)

Thanks a ton ! This worked.
