compare and find index of matching elements of two matrices

I have two matrices say A=[2.4 2.4] and B=[ 2.4 2.6 3.7 2.4; 3 2.4 4.1 3.6] each element of A compared with each row of B.If the element of A is present in the matrix B, then the index of the element in B should be returned.

In more detail, suppose the first element of A i.e., 2.4 is compared with the first row of B. As it is present in B, the index of the element 2.4 in the B matrix is returned.
