            I want to compare a vector with a matrix having mutiple rows. Exact situation with coding and result described below:
For vector:
a vector of a single row and three columns shown below
coding        c = [];      c(end+1,:)=[k1 k2 k3];      disp (c);
result          2.4 2.5 3.9
For matrix:
coding        b= [];       b(end+1,:)=[Kp Ki k3 k4 k5];   disp(b);
result          1   1    2.9   2.7   3.6
                   1   2     3.5  3.9   3.9
    ................. so on.
Now, problem is: 
Compare matrix column 3, 4 and 5 with a vector (2.4 2.5 3.9). Note, vector values are used as reference. In return, want a result of values in matrix that are equal and less than the values of vector. 
In more detail: If any value of column 3 in matrix is equal or less than the 1st value vector then result display. But need a result that import complete row of this matrix. Similarly, if any value of column 4 in matrix is equal or less than the 2nd value vector then result display complete row of this matrix.
All these combinations displayed in a final matrix. Means final matrix contain all reults of import rows find after comparison.

				You would potentially have several results for matching column 3, a different number for matching column 4, and so on. Are all of these to go into the same output matrix, without any division between the sections ? Or when you say "display" do you mean to the command window, not storing in a matrix?

        yourMatrix=[randi(2,20,2),5*rand(20,3)];
yourVector=5*rand(20,3);
newMatrix=yourMatrix(yourMatrix(:,3)<=yourVector(1)|yourMatrix(:,4)<=yourVector(2)...
    |yourMatrix(:,5)<=yourVector(5),:);
