We have generated key from combined tent and sine map and converted them into a matrix using "vec2mat()" of size 32*96. In this how can we extract the row and column number of a particular value.

If A is your matrix
[r,c] = find(A==V)
will return the row(s) and column(s) where A matches the value V.
