Dear all I have a two column matrix such as:

A=[12 44; 56 78; 81 100; 110 200; 210 300;450 500; 600 710]

this matrix rows contains interval boundaries in points of a time series (electromyography)

A =

    12    44
    56    78
    81   100
   110   200
   210   300
   450   500
   600   710
now I have a control vector such as:
vec_control=[60 115 460]
I want to eliminate the rows in A whose boundaries contain any value in vec_control, so to obtain:
A_new =
    12    44
    81   100
   210   300
   600   710
Any help please?
Many thanks in advance!!
