Undefined operator '/' for input arguments of type 'cell'.

Dear all,

I have this line of code:

Contours{1}={gsubtract(shape.thorax(1:end-1,:),params.Norm)/params.Norm};

And still this error message: Undefined operator '/' for input arguments of type 'cell'.

I figured out how solve operator '-' (by gsubtract), but I don´t know how I solve operator '/'.

This is my whole code:

function [fmdl,img_okoli] = Newmodel(params,shape)
Contours{1}={gsubtract(shape.thorax(1:end-1,:),params.Norm)/params.Norm};

cnt=2;
if exits(shape.leftLung)
 Contours{cnt}={(shape.leftLung(1:end-1,:)-params.Norm)/params.Norm};
   cnt = cnt + 1;
end

cnt=2;
if exits(shape.rightLung)
 Contours{cnt}={(shape.rightLung(1:end-1,:)-params.Norm)/params.Norm};
   cnt = cnt + 1;
end

thorax_shape = {params.Height,                                % výška
          Contours,  % kontury
          1,                      % použití defaultních vrcholů 
          params.Refi};                   % maxh (zjemnění )

elec_pos = [ params.NumEl ,                  % počet elektrod
             params.DistEl,                   % vzdálenost mezi elektrodami
             0.5]';               % v z rovině

elec_shape = [params.RadEl,                % poloměr
              params.ShapeEl,                   % kulaté elektrody 
              params.RefiEl]';             % maxh (zjemnění)

fmdl = ng_mk_extruded_model(thorax_shape, elec_pos, elec_shape);
img_okoli=mk_image(fmdl,1);

end

Can you advise me? Thank you for your answers.

[ES]

division or / is not defined for cell datatype. So make the numerator and denominator to matrix types[using cell2mat].

[Veronika]

Okay, I used cell2mat, but something is still wrong. This is the error message:

Cell contents reference from a non-cell array object.
Error in Newmodel (line 3)
Contours{1}={gsubtract(shape.thorax(1:end-1,:),cell2mat(params.Norm))/cell2mat(params.Norm)};

THis is the line of my code:

function [fmdl,img_okoli] = Newmodel(params,shape)

Contours{1}={gsubtract(shape.thorax(1:end-1,:),cell2mat(params.Norm))/cell2mat(params.Norm)};

Where is problem?

[Image Analyst]

Put these lines in before it crashes and tell us what it shows in the command window:

whos params.Norm
celldisp(params.Norm);

[Veronika]

Command window:

Error using celldisp (line 14)
Must be a cell array.
Error in Newmodel (line 3)
celldisp(params.Norm);

[Walter Roberson]

It is probably the shape.thorax(1:end-1,:) that is the cell array.
