using find function

im having a problem to find the correct value that i desire. im trying to plot graph for beamwidth for uniform array. but, the problem is that when i use the find function to find the angles which has -3dB gain, there is an error. so, i rounded up the -3dB angles to make it easy to use the find function. then, the rounded is not accrurate and consist some undesired value. example: p=-3.0041 -3.2098 -3.2000. I rounded up the value and it makes the value to become p= -3 -3 -3. hence, it contains some undesired value and makes it complicate to plot the graph. can anyone help to overcome this problem.

If I understand you correctly, try to round your vector roughly this way:
round(p*100)/100
or use find something like that:
find(abs(p-3)<0.001)
