name of the maths function that gives one if two inputs are similar

Question

What is the name of this function? ${\delta\left(y_j,c_k\right) = 1}$ if ${y_j = c_k}$, ${0}$ otherwise.?

similar is not the same as equal. – lhf Aug 30 '13 at 13:37 — lhf, Aug 30 '13 at 13:37

This is quite similar to Kronecker's delta.
