Addressing issue #59 magnitude and phase function for Matlab #76

Closed Alex-McVey closed 2 years ago

Alex-McVey commented 2 years ago

Magnitude and phase function developed in Matlab with identical function to the one available in Python.

The following code can be used to test 2D function in Matlab magnitude = 9; y = sqrt(1/2*magnitude^2);, x=y; phase = atan2(y,x); [mag, theta] = magnitude_phase({x; y}); assert(all(magnitude == mag)) assert(all(phase == theta)) xx = [x,x]; yy = [y,y]; [mag, theta] = magnitude_phase({xx; yy}); assert(all(magnitude == mag)) assert(all(phase == theta))

The following code can be used to test 3D function in Matlab magnitude = 9; y = sqrt(1/3*magnitude^2);, x=y;, z=y; phase1 = atan2(y,x); phase2 = atan2(sqrt(x.^2 + y.^2),z); [mag, theta, phi] = magnitude_phase({x; y; z}); assert(all(magnitude == mag)) assert(all(phase1 == theta)) assert(all(phase2 == phi)) xx = [x,x]; yy = [y,y]; zz = [z,z]; [mag, theta, phi] = magnitude_phase({xx; yy; zz}); assert(all(magnitude == mag)) assert(all(phase1 == theta)) assert(all(phase2 == phi))

@Alex-McVey similarly to your other PR, this will need test(s) written.
