MATLAB: How to convert character array to cell array

char array

hello, i have a char array of size 1280 * 8 … values like 11111111 01010101 10100101 …….. 01010101 Now i want as 1*10240 cell array (since 1280 * 8 =10240)…output must be 1,1,1,1,1,1,1,1,0,1,0,1,0,1,0,1…..i used str2num ..but they were being conatanated as vertical..i want to conctanate horizantally/..

MATLAB: How to calculate index of minimum value in cell array

>> m1{1,1} = [0.34463,0.3276,0.3615,0.3446,0.3559,0.3389,0.3389,0.3446];
>> m1{1,2} = [0.36723,0.3333,0.3615,0.3615,0.3446,0.3559,0.3163,0.3333];
>> m1{2,1} = [0.3390];
>> m1{2,2} = 5:9;

An efficient method is to use min once:

>> [val,idx] = min([m1{:}]);
>> len = [0;cumsum(cellfun('length',m1(:)))];
>> idc = find(len>=idx,1,'first')-1;      % cell index
>> idv = idx-len(idc);                    % vector index

The minimum is thus:

>> val
val =  0.31630

and the minimum can be obtained using those indices:

>> m1{idc}(idv)
ans =  0.31630

You can get the cell array row and column indices by using ind2sub:

>> [row,col] = ind2sub(size(m1),idc)
row =  1
col =  2

Try this

>> num2cell( magic(5), 1 )
ans =
  1×5 cell array
  Columns 1 through 4
    {5×1 double}    {5×1 double}    {5×1 double}    {5×1 double}
  Column 5
    {5×1 double}
>>

I assume

B = num2cell( A, 1 );

solves your problem
