MATLAB: I have a matrix which is [y1 x1 y2 x2 y3 x3…….]. The size variable depends on the input, I wanna extract y(i) and x(i) seperately from this matrix.

a=1:10
y=a(1:2:end)'
x=a(2:2:end)'

MATLAB: Find values between constants in vector

idx = X >= a & X <= b;

where X is your vector, a is the lower bound, b is the upper bound. This will be their logical values. If you want numerical indices:

find(idx)
