I have a matix 80x1. Now i want band of values to be executed:
The band is: 1-14, 29-33, 40-54, 69-73.
It should ignore all the values not included in the above band.
For this, I tried if-loop with the conditions like,
if k < 14 || k > 29 && k < 33 || k > 40 && k < 54|| k > 69 && k < 73
then...
end
However, this does not work. i mean, it works fine only upto k=33
Any help?

k=1:80
idx = ( k >= 1 & k <= 14 | k >=29 & k <= 33 | k >= 69 & k <=73)
k(idx)=[]

see the above example it finds the index of the values that falls inside that band and in the next step those values are removed , which in this case is your desired result

What difference does that make?
& evaluates both conditions but && evaluates only if right hand side is true for detailed explanation see difference between & and &&
Loop is not necessary for this , smoother and efficient by this way though
