I have an array of 90x2 and may variable is 1x2. i want to set an if statment which checks if k == array or k is an element of array. I am aware there is ismember function but I cant seem to make that work for me

It doesn't make sense to check if k == array, because they are different sizes.
k can't be an element of the array, because each element of the array is a scalar, but k is 1x2. Do you want to check whether k is a row of the array?
What actually goes wrong when you use ismember? Have you tried the 'rows' option?

The description is ambiguous as to what "is an element of array" means for a two element vector, but I assumed that the desired end result is to check if any matrix row matches the variable.
>> A = [0,1;2,3;4,5;6,7;8,9];
>> ismember([4,5],A,'rows')
ans =
1
>> ismember([99,100],A,'rows')
ans =
0
