Matching pair to some reference value

Dear All

I need help to find out the pairs which are equal to the some reference value e.g my data is given as

 A(i)=d2_f(i);
B=([e1(i);e2(i);e3(i);e4(i);e5(i);e6(i);e7(i);e8(i);e9(i);e10(i);e11(i)]);

i want to find out which pairs in B can meet the value of A

Thanks in advance for answering

Answer 1

[KSSV]

tol = 10^-6 ; 
idx = abs(B-A)<=tol ;
[A B(idx')]

[Amin Waqas]

how i can use this under loop

for i=1:1:17520

as value of A and B are changing from one i- index to other i-index

[KSSV]

Is A always a single number?

[Amin Waqas]

yes

[KSSV]

tol = 10^-6 ; 
iwant = cell(17520,1) ; 
for i = 1:17520
    A=d2_f(i);
    B=([e1(i);e2(i);e3(i);e4(i);e5(i);e6(i);e7(i);e8(i);e9(i);e10(i);e11(i)]); 
    idx = abs(B-A)<=tol ;    
    iwant{i} = [A B(idx')] ;
end

You may read about ismembertol and avoid loop. Read about it.

Following error is reported while running this segment

Error using horzcat

Dimensions of matrices being concatenated are not consistent.

Error in asdsad (line 96)

iwant{i} = [A B(idx')]

[KSSV]

The error is simple.......see A is a single number and if B is row matrix..no error...if it is column matrix there will be error. Remove the transpose in idx.

iwant{i} = [A B(idx)]

Simply use ismembertol()
