Dear all, The objective was to rename a table which located inside a different cell container. To make things compact, the CELLFUNC was used. However, I MATLAB output the following error
Input #2 expected to be a cell array, was char instead.
May I know what I have been missing?
Thanks in advance for any advice
The code are
load('nonChange.mat')
varname={'combination','specificity','sensitivity','accuracy','spPsn'};
ddTrans = cellfun(@array2table,'VariableNames',varname,nonChange_Cell,'UniformOutput',false);

To solve the first problem, replace the cellfun statement by
ddTrans = cellfun( @(v,m) array2table(m,'VariableNames',v) ...
, varname, nonChange_Cell,'UniformOutput',false );
Next problem: the sizes don't match
>> whos nonChange_Cell varname
Name Size Bytes Class Attributes
nonChange_Cell 33x24 92993344 cell
varname 1x5 652 cell
  • What do you expect ddTrans to become?
  • Do you want to create 792 tables all with the same variable names?
If yes, try to replace the cellfun statement by
ddTrans = cellfun( @(m) array2table(m,'VariableNames',varname) ...
, nonChange_Cell,'UniformOutput',false );
inspect result
>> ddTrans{2,1}
ans =
combination specificity sensitivity accuracy spPsn
