Hi,
I have an array with 2*100 size. i want to check that a variable k with the 1st row of the array that k is equal or not to any value in the 1st row.
A=[3 4 6 3 5 4 2 56 7 7; 56 34 2 4 6 7 7 78];
variable k=3;
so i want to check k with A(1,1);A(1,2);A(1,3);......;A(1,n)

I suggest comparing the difference of A in k with a very small number:
f=abs(k-A(1,:))<2*eps
This avoids a couple of numerical surprises...
