Convert logical values into numeric values

I have a cell array 20000 rows and 20 columns with logical values:

A={0 0 0 0 1 0...
   0 0 1 0 0 0 
   1 0 0 0 0 0
   0 1 0 0 0 0 ...}

And I would like to convert this array into numeric values of 1 and 0. Can someone help me? Thank you.

Answer 1

This works:

B = double(cell2mat(A));

The cell2mat call converts it from a cell to a logical array, and double converts it to a double array.

I wrote small code

for a=1:number of rows
  for b=1:number of columns
      if A(a,b)==true
         new_matrix(a,b)=1;
      else
          new_matrix(a,b)=0;
      end
   end
end

This doesn't work either. Have you tried it?

??? Undefined function or method 'eq' for input arguments of type 'cell'.

[Julotek]

for a=1:number of rows
  for b=1:number of columns
      if A{a,b}
         new_matrix(a,b)=1;
      else
          new_matrix(a,b)=0;
      end
   end
end

That should work but it is maybe too complicated for you need.

double(A) works

Answer 4

Try this:

B = cell2mat(A).*1;

[James Tursa]

I just did. It doesn't work:

>> A = {1 0;0 1}
A = 
    [1]    [0]
    [0]    [1]
>> B = A.*1;
Undefined operator '.*' for input arguments of type 'cell'.

@James —

Yours confirms my result:

A = {[1 0 1 1 0] == 1};
B = A.*1;

It throws the same error.

[Jonathan Patao]

you're right, my fault. you need to convert from cell first. try:

B = cell2mat(A).*1;
