MATLAB: Convert a cell of ‘yes’ and ‘no’ into array of 1 and 0

Hi guys,

I have a problem converting a cell of 'yes' and 'no' (string) into array of 1 and 0 (double).

Lets say I have the following cell:

Data = 4×1 cell array

{'no' }

{'yes'}

{'no' }

{'yes'}

The output should be:

Data = [0;1;0;1]

I have the following code that works when the cell only contains 'yes' but does not when it contains a 'no'.

for i=1:length(Data)
if Data{i}=='yes'
    Data{i}=1;
else
    Data{i}=0;
end
end
Data=cell2mat(Data);

out = strcmpi(Data,'yes')

A=[0;1;0;1]
options = {'no';'yes'}; 
s = options(A+1)

or perhaps you'd benefit from working with logical arrays,

TF = logical(A);

As stated in the documentation you can use the == operator to select elements in a categorical array that are in a particular category.

>> A = categorical({'yes','yes','no','no','yes','no'}) 
A = 
  1×6 categorical array
     yes      yes      no      no      yes      no

>> A == 'yes'
ans =
  1×6 logical array
   1   1   0   0   1   0
