MATLAB: Find cell containing part of a string.

cell arrayMATLAB

I have a cell "A" of strings like {'A0_V2'; 'A0_V1'; 'B2_V4';…}. I want to find which numbers of A contains 'A0'. The answer can be ans = (1, 2).

Try contains():

A = {'A0_V2'; 'A0_V1'; 'B2_V4'}
rowsWithString = contains(A, 'A0')

Hi Leo,

To add to Walter's comment, (if I understand what you are trying to do correctly), I would also recommend looking into the native2unicode function or the reverse (unicode2native). These combined with the char function can let you insert a variety of characters in as plot markers. For example:

%*** Create A Plot With NO Markers ***
x = 1:40;
y = rand( 1, 40 );
plot( x, y );
axis( [0.5, 40.5, -0.1, 1.1 ] );
%*** Add Filled Markers from 1 to 10 (u+2776 to u+277F) ***
for i = 1:10
     nativeValue = char( hex2dec( '2776' ) + i - 1);               %Native format (bit/byte arrangement)
     unicodeValue = native2unicode( nativeValue, 'UTF-16' );    %Convert to Unicode 16 format
       text( x( i + 20 ), y ( i + 20 ),...                        %Position of font character        
          unicodeValue,...       
          'FontSize',12,...                                       %Set font size to 12
          'HorizontalAlignment', 'Center',...                     %Center character on point 
          'VerticalAlignment', 'Middle' );
  end

I apologize if I misunderstood your question, but hope this is helpful!

MATLAB: How to find a certain string in a cell with variable size

>> TempCell = {{'a1','a2'},{'a3','a4','a8','a7'},{'a2','a1'},{'a9'}};
>> out = TempCell(~cellfun(@(c)any(strcmp('a1',c)),TempCell));
>> out{:}
ans = 
    'a3'    'a4'    'a8'    'a7'
ans = 
    'a9'

Using a loop will actually be more efficient (and faster), but cellfun is much more compact code.
