Hi :) I have a vector let's say A=randi(10,1,100)' and whenever I find a value equal to 1 I want to set that value and the following 2 values to NaN.
For another case I need to do the same but whenever there are 4 ones in row, then I need to do set to NaN the 2 values following the last 1.
Does anyone know a way of doing that?

A=randi(10,1,10).'
idx=find(A==1);
A([idx idx+1 idx+2])=NaN
