MATLAB: How can i count number of zeroes in a martix(containing elements 0s and 1s only) which is below any 1s(means in a column top to bottom , if 0 comes then dont count if 1 comes then count whole 0s below that 1.

matrix array

A(:,:,1) =

     5     7     8
     0     1     9
     4     3     6

A(:,:,2) =

     1     0     4
     3     5     6
     9     8     7

>> M = randi(0:1,5,6)
M =
   0   1   1   1   0   1
   0   1   0   0   0   1
   1   0   0   0   1   0
   1   1   1   0   0   1
   0   0   0   1   1   1
>> sum(cumsum(M,1) & M==0, 1)
ans =

MATLAB: Adding 0s and 1s to Bit Data

From what I understand, it sounds like you need to generate a m x n x 3 matrix and the easiest way might be to simply do a repmat of your matrix. It should look something like this:

output_matrix = repmat(input_matrix,1,1,3);

When writing to file, the values have to be written depth-wise so use:

fprintf('%d %d %d\n', permute(output_matrix,[3 2 1]))

I hope this helps!
