Syntax

lambdaWrapped = wrapToPi(lambda)

Description

example

lambdaWrapped= wrapToPi(lambda)wraps angles inlambda, in radians, to the interval[−pi, pi]such thatpimaps topiand−pimaps to−pi. In general, odd, positive multiples ofpimap topiand odd, negative multiples ofpimap to−pi.

Specify a short list of angles to wrap.

lambda = [-2*pi -pi-0.1 -pi -2.8 3.1 pi pi+1 2*pi];

Wrap the angles to the range [- π , π ] radians.

lambdaWrapped = wrapToPi(lambda)
lambdaWrapped =1×80 3.0416 -3.1416 -2.8000 3.1000 3.1416 -2.1416 0

Specify a second list of angles, and wrap them.

lambda2 = -10:0.1:10; lambda2Wrapped = wrapToPi(lambda2);

Plot the wrapped angles. The wrapped angles stay in the range [- π , π ] radians.

plot(lambda2,lambda2Wrapped) xlabel("Angle (radians)") ylabel("Wrapped Angle (radians)") gridon

Figure contains an axes object. The axes object contains an object of type line.

Input Arguments
