Re: [Laurent_R] A file parsing and 2D array/matrix problem.

Laurent and Chris , Thanks a ton for sharing practical views and extensively exploring other realms of the problem space.
Yes the supermatrix will be very very sparse. But let me add the last element to the problem posed here by me.
I need to create 10 such supermatrices and concatenate them taking two at a time. For instance till now I'm able to create a text file for each of these 10 supermatrices.
Now there's the last piece of puzzle. I have created 10 such matrices (with obviously same number of rows and column).
Now the problem is that I have to concatenate (OR logic operation) two such matrices,
INPUT = Two matrices A,B (each saved in separate text files) of same row and column
OUTPUT = A single matrix C ( C[j] = A[j] OR B[j] )
==============INPUT=======
MAT - A
1875 2809 3182 3419
2809 - 1 1 -
3182 1 - - -
3186 1 1 - -
3485 - - - -
3486 - - - -
MAT - B
1875 2809 3182 3419
2809 1 - - 1
3182 - - - -
3186 - 1 1 -
3485 - - - -
3486 - 1 - 1
========== OUTPUT===========
MAT - C
1875 2809 3182 3419
2809 1 1 1 1
3182 1 - - -
3186 1 1 1 -
3485 - - - -
3486 - 1 - 1
I.e. an element of matrix will be one if either of the corresponding element of A or B is one.
