P=[1 32 3 78 5 6 7 8 9 10] ;P is my original array which has the size is 1*10; I have Q=[2 4 7];I want delete in Q array value in P array; My expect output is P=[ 1 3 5 6 8 9 10] by using for loop only because of the size of Q array may be change ;P(:,[Q(1) Q(2) Q(3)])=[] this command use only the size of Q array is 1*3 .So I need for loop logic which is common of any array size.

You can omit the square brackets and 1:end :
P(Q)=[]

If you want to delete the values at the indicies in P, that are specified in Q use the answer from Madhan above. If you need to delete the values in P specified in Q use:
P(ismember(P,Q))=[]
