selecting particular elements from a cell array

Dear all,

I have the following cell array

A={

    }

I want to select all the numbers from the last 2 columns that correspond to the string variables of column 3 (in the above example 'B1' 'B2' 'B3') AND the the string variables of column 1 (in the above example 'MN1' 'MN2')

So, I want to obtain

A_new={

 'MN1'  [      'B1']   [2.9102]    [28.2414]
 'MN1'  [      'B1']   [2.9961]    [29.4252]
 'MN1'  [      'B1'] [3.0740]    [29.4386]
 'MN1' [      'B2']  [2.8701]    [27.8087]
'MN1'   [      'B2']  [2.9805]    [29.6135]
 'MN1'      [      'B2'] [2.9793]    [29.5466]
   'MN1'    [      'B3'] [2.9102]    [28.2414]
'MN1'    [      'B3']  [2.9961]    [29.4252]
'MN1'  [      'B3']  [3.0740]    [29.4386]
'MN1' [      'B1']  [2.8701]    [27.8087]
'MN1'   [      'B1']  [2.9805]    [29.6135]
 'MN1'   [      'B1']  [2.9793]    [29.5466]  
 'MN1'  [      'B2']  [2.9102]    [28.2414]
  'MN1'  [      'B2']  [2.9961]    [29.4252]
'MN1'  [      'B2']  [3.0740]    [29.4386]
 'MN1'   [      'B3']  [2.8701]    [27.8087]
'MN1'   [      'B3'] [2.9805]    [29.6135]
'MN1' [      'B3'] [2.9793]    [29.5466] 
'MN2' [      'B1'] [2.8701]    [27.8087]
  'MN2'   [      'B1']  [2.9805]    [29.6135]
 'MN2'   [      'B1'] [2.9793]    [29.5466]  
 'MN2'   [      'B2'] [2.9102]    [28.2414]
'MN2'  [      'B2']   [2.9961]    [29.4252]
'MN2'   [      'B2']   [3.0740]    [29.4386]
'MN2'    [      'B3'] [2.8701]    [27.8087]
'MN2'   [      'B3'] [2.9805]    [29.6135]
'MN2'    [      'B3'] [2.9793]    [29.5466] }

   I am looking for a code that can identify and select   all 
   the string variables  of column 1 AND string variables  of column 3 and then find the numbers that correspond
   to these string variables

Is there a way of doing that?

   thanks

[Daniel Shub]

There are a number of ways of doing this. What have you tried so far?

Answer 1

[Matt Fig]

idx = all(cellfun(@(x) ~isequal(x,0),A(:,[1 3])),2)
R = A(idx,[1 3 4 5])

[Andrei Bobrov]

A(all(cellfun(@ischar,A(:,[2,3])),2),[1,3:end])
