Dear Math Group,
I have matrix M and matrix N
for example
M={{1,2},{3,4},{5,6},{7,8}}
N={{1,8},{5,0},{9,7}}
(dimension is diffrent)
I need to make new matrixes which include only this rows from matrix M and
matrix N for which firsts elements are the same in both matrix (M and N).
so I need
M1={{1,2},{5,6}}
N1={{1,8},{5,0}}
Elements of matrix are real (not always integer)
Please for help
Peter
