MATLAB: Deleting specific rows in a matrix

MATLABmatrix row deletion

I want to delete rows that contain element of value 0
for example in the following matrix B
row 3, 4 ,5 contains a zero valued element. So I want to delete these rows and the resultant matrix would be 2*3 .
How can I remove these particular rows
   120   150   200
   250   300   350
   420   450     0
     0   100   400
   450     0   420

Best Answer

A=[120   150   200
   250   300   350
   420   450     0
     0   100   400
   450     0   420]
index=find(nanmean(A==0,2))
A(index,:)=[]
Below is the output of index and A (after removing the rows having zero value)
index =
     3
     4
     5
A =
   120   150   200
   250   300   350
