I want to create a row of a matrix which consist of 16 zeros and random replace 4 of the first 8 elements with ones and 2 of the last 8 elements with ones.
i.e A = [ 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ;]
Then B= [ 1 0 0 1 1 0 0 1 0 0 1 0 0 1 0 0 ; ]
The ones should be replaced randomly in their positions as explained before.
Any help could be useful.
Thanks in advance !

A = [ 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ]
B=A
B([randperm(8,4) randperm(8,2)+8])=1
