conversion to cell from double

Hello,

I'm trying to compile data into a matrix or cell array, but I've settled on a cell array in order to index (within the array) the data I'm compiling with it's source (a string that indicates a name).

I've included some code to help. (chandata starts as a ~1000 row by 10 row matrix [double]):

function [] = KsnEro(wname, sname, bname)

%The purpose of this script is to load Ksn files produced by 'geomorphtools'
% and match it to erosion values from Balco, 2013 paper.

%wname = watershed name
%sname = stream name
%bname = Stream designation in Balco Sampling system

%Load stream data
matlab_workdir = strcat('/Volumes/vonDassow/DEM_Analysis/Balco/', wname)

load(strcat(sname, '_chandata'))
n = size(chandata,1);
nameMat = repmat({sname}, n, 1);
ksn_all = chandata(:,8);
ksn_allmat = num2cell(ksn_all);

%Load Erosion Rate Data --> Must already be a Matlab file (table).

load('/Volumes/vonDassow/DEM_Analysis/Balco/Balco_ErosionRates.mat')

Erate = ones(n,1);

E1 = length(BalcoEro);

% % % Erate = num2cell(Erate)

%strmatch bname to BalcoEro, extract row of str match

for i = 1:E1

      if strmatch(BalcoEro(i,1), bname) == 1

          fprintf('It worked')

          BCurrent = BalcoEro(i,2);        %BCurrent = value being taken.

          BCurrent = cell2mat(BCurrent);

          Erate(:,1) = BCurrent

          break

      else 

          fprintf('It did not work')

      end;

end

%sdata is for only 1 strea, i.e. Alsea1, Alsea2, etc.

sdata = cell(n,3);

sdata(:,1) = nameMat;

sdata(:,2) = ksn_allmat;

sdata(:,3) = Erate;

My error occurs in this last line 'sdata(:,3) = Erate;', below

Conversion to cell from double is not possible.

Error in KsnEro (line 43)
sdata(:,3) = Erate;

[per isakson]

Replace

sdata(:,3) = Erate;

by

sdata(:,3) = {Erate};

might help. Or better

dbstop if error

and inspect the types of the variable values involved
