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

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
