MATLAB: Detecting and eliminating numbers from a cell matrix that contains NaNs and string characters

Question

Dear all, I have a cell matrix An example is the following

total(1:20,1:2)

ans =

    [                NaN]    [          NaN]
    [                NaN]    [          NaN]
    [                NaN]    [          NaN]
    'England'                [          NaN]
    [                NaN]    [          NaN]
    [                NaN]    [          NaN]
    ' AUSTRIA'          '  SMOKES'
              [1x20 char]    'NIKE'      
              [1x26 char]        [1x46 char]
              [1x26 char]        [1x41 char]
              [1x26 char]        [1x38 char]
              [1x20 char]    'GOODYS'      
              [1x26 char]        [1x56 char]
              [1x26 char]        [1x48 char]
              [1x26 char]        [1x47 char]
    ' BAND 1'          'HIT'       
    ' BAND 2 KA 1'        [1x39 char]
    ' BAND 2 KA 2'        [1x42 char]
    ' BAND 2 KA 3'        [1x47 char]
    ' BAND 2 KA 4'        'YES'

The problem is that sometimes these 2 columns contain numbers in some cells, like zero, and this distorts the analysis. Is it possible to detect such numbers and if exist eliminate then from the corresponding cells?

thanks

Answer 1

A = {[         NaN]    [     NaN]
    [         NaN]    [     NaN]
    [         NaN]    [     NaN]
    'England'         [     NaN]
    [         NaN]    [     NaN]
    [         NaN]    [     NaN]
    ' AUSTRIA'        '  SMOKES'
    'tetete'          'NIKE'    
    'jhjh khkhkh'     'GOODYS'  
    ' BAND 1'         'HIT'     
    ' BAND 2 KA 1'    'eerrrr'  
    ' BAND 2 KA 2'    'dddddd'  
    ' BAND 2 KA 3'    [     NaN]
    ' BAND 2 KA 4'    'YES' };

eg

A(cellfun(@(x)isnumeric(x)&~all(isnan(x)),A)) = {NaN};

OR just

A(cellfun(@(x)isnumeric(x),A)) = {NaN};
