How to produce an array that displays the common data values in other arrays?

1 Ansicht (letzte 30 Tage)
I am trying to find a way to make a resulting array that displays all of the common values (in the same row/colomn) that multiple arrays share. I attached an example photo to explain what I mean. So, as you can see in the photo, I am trying to produce the resulting array called "Total" by using the shared values from A, B, and C.

A = [1,1,0;1,1,1;0,1,1]
A = 3x3
1 1 0 1 1 1 0 1 1

B = [1,0,1;0,1,0;1,1,1]
B = 3x3
1 0 1 0 1 0 1 1 1

C = [1,1,1;1,1,0;1,1,1]
C = 3x3
1 1 1 1 1 0 1 1 1
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
D = double(A & B & C)
D = 3x3
1 0 0 0 1 0 0 1 1

Your question is not clear enogh
I have changed a,b &c to hold also other values than 0,1
The result is :
  • "ind" holding the indexes of matching values and
  • "common" - holding the actual common values
a = [5 1 0;1 22 1;0 0 3];
b = [5 0 1;0 22 0; 1 0 3];
c = [5 1 1;1 22 0;1 0 3];
a_and_b = a==b;
b_and_c = b==c;
a_and_b_and_c = a_and_b == b_and_c;
ind = find(a_and_b_and_c)
ind = 6x1
1 2 4 5 6 9
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
common = a(a_and_b_and_c)
common = 6x1
5 1 1 22 0 3

.. and to get the total (logical):
a = [5 1 0;1 22 1;0 0 3];
b = [5 0 1;0 22 0; 1 0 3];
c = [5 1 1;1 22 0;1 0 3];
a_and_b = a==b;
b_and_c = b==c;
a_and_b_and_c = a_and_b == b_and_c;
ind = find(a_and_b_and_c);
total = false(size(a));
total(ind) = true;
Unrecognized function or variable 'a'.
