Unique and vectors last variable (simulink)

I got up to 32 vectors with six variables. I would like to remove whole vectors with multiple last variables(6) and keep the rest.

C01 = uint32([1;0;0;0;0;BANK1]);

C02 = uint32([0;1;0;0;0;BANK2]);

C03 = uint32([0;0;1;0;0;BANK3]);

C04 = uint32([0;0;0;1;0;BANK4]);

C05 = uint32([0;0;0;0;1;BANK5]);

Les's say bank 1=5, 2=10, 3=10, 4=20 and 5=0. So the idea is that bank 2 or 3 should be removed, since the value(6) has already been used earlier. But I need to have other vectors safe as whole.

Saved as output:

1 0 0 0 0 5

0 1 0 0 0 10

0 0 0 1 0 20

0 0 0 0 1 0

Removed:

0 0 1 0 0 10

with unique I only know how to check the final variable(6) but everything else of the vector will be lost during process.

Thanks!

How is this related to Simulink? Can you post an example model showing what you are trying to do?

Maybe use this approach in your MATLAB function block or add a separate MATLAB function block to modify the CONNECTION_OPTIONS matrix? Here I call unique twice. Use the 'stable' argument the first time so that column index order in the ic return vector is preserved. Then call unique on that column index vector to remove the repeated values.

>> C = [zeros(5,1) eye(5)]

C =

0 1 0 0 0 0

0 0 1 0 0 0

0 0 0 1 0 0

0 0 0 0 1 0

0 0 0 0 0 1

>> CXX = [C; BANK]

CXX =

0 1 0 0 0 0

0 0 1 0 0 0

0 0 0 1 0 0

0 0 0 0 1 0

0 0 0 0 0 1

0 5 10 10 20 0

>> [c, ia, ic] = unique(CXX(end,:), 'stable')

c =

0 5 10 20

ia =

1

2

3

5

ic =

1

2

3

3

4

1

>> CXX(:,unique(ia))

ans =

0 1 0 0

0 0 1 0

0 0 0 0

0 0 0 1

0 0 0 0

0 5 10 20

Ok, thanks for your help!! It seems to be working. With first 6 out of 32 options this is how my end result looks!

function OUTPUT = PFC(C1,C2,C3,C4,C5)

OBJX = [ 0 1 0 0 0 0

0 0 1 0 0 0

0 0 0 1 0 0

0 0 0 0 1 0

0 0 0 0 0 1 ];

CAPX = [ OBJX; 0 C1 C2 C3 C4 C5 ];

[~, ia, ~] = unique(CAPX(end,:), 'stable');

OUTPUT = uint32(CAPX(:,unique(ia)));
