Problem 59721. finding vector pair with min angle between them
given a matrix with more than one row , compare row vectors of the given matrix and find the pair with the minumum angle between them , "without using the dot fucntion" 
you can find the angle from the following formula
 θ = cos-1 [ (a. b) / (|a| |b|) ]
the product between the two vectors is the dot product 
a⋅b=∑(ai)*(bi)   from i=1 to n
the length of a vector is the square root of the sum of the squares of the components
