how to get value except one row which in_zone value is 2

   in_zone     IDX       X0        Y0

   30.0000    3.0000   33.4992   80.5353

ch =2
cl1=7

    2.0000   36.0104   61.2907
    3.0000   33.9572   63.7608
   25.0000   35.0651   45.3938

Now I get all value from column 1(in_zone),3(X0),4(Y0) which contain 7 in 2(IDX) column

but I get all value except ch value and its corresponding values.

now wish to get only

   3.0000   33.9572   63.7608
   25.0000   35.0651   45.3938

Answer 1

[the cyclist]

Now I understand your question better. Here is how to do it in one line:

A = XY1(XY1(:,1)~=ch & XY1(:,2)==cl1,[1,3,4])

Here is the same thing done is multiple steps:

% Index to values where first column is _not_ equal to _ch_:
idx1 = XY1(:,1)~=ch;

% Index to values where second column _is_ equal to _cl1_:
idx2 = XY1(:,2)==cl1;

% Index to values where _both_ conditions are true:
idx_both = idx1 & idx2;

% Use the index to get the rows:
A = XY1(idx_both,[1,3,4])

thanks cyclist

Answer 2

A(not(A(:,1)==2),:)

[singh]

cyclist firstly A filter those value which hold cl1 in IDX and now i wish to again filter the first column of result A and who has contain ch value in first column except whole row and get the rest data.
