MATLAB: How to remove certain elements in 2D array

matrix array

i have a variable 'c' in size of 4×2 c=[4 2; 5 3; 3 6; 4 7;] and another variable 'd' in size of 2×2 d=[4 2; 3 6;]. Compare two variables( c and d)and remove elements of 'd'variable in Variable 'c' and how get final output F=[5 3; 4 7;]?

Best Answer

use setdiff

F = setdiff (c, d, 'rows')

Hi,

how about this:

TFunct=zeros(1700,1); % or whatever
for i = 1 : 17000
TFunct(i,1)=mean([TFunct1(i,1),TFunct2(i,1),TFunct3(i,1)]);
end

or without a loop you can use this:

>> A=[1 2;2 3;3 4;4 5;5 6]
A =
       1     2
       2     3
       3     4
       4     5
       5     6
  >> B=[2 3;3 4;4 5;5 6;6 7]
B =
       2     3
       3     4
       4     5
       5     6
       6     7
  >> C=[3 4;4 5;5 6;6 7;7 8]
C =
       3     4
       4     5
       5     6
       6     7
       7     8
  >> D=[A(:,1)';B(:,1)';C(:,1)']
D =
       1     2     3     4     5
       2     3     4     5     6
       3     4     5     6     7
>> mean(D)
ans =
       2     3     4     5     6
