How to EFFICIENTLY name multiple tables located inside a different cells

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);

@balandong: you should also load into a variable, rather than directly into the workspace.

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 
    ___________    ___________    ___________    ________    _______
    1              0.71429        0.38462        0.53191     0.54945
    2                    1              0        0.44681         0.5
