\* Fix a bug where noise was added to the power spectral density matrix for the optimal observation filter calculations in the noiseless case.\
### v0.2.0 ###
**Utilities**
\+ Added a bisection method for single-valued functions.
\* Improved rotation matrix calculation function with degrees and radian calculations available.
\+ Added function to calculate a double-sided spectrum from a single-sided spectrum.
\+ Added a function to calculate the intersection of three vectors.
\+ Added a pair of functions to check for even or odd elements.
\+ Added a function to pick values from a vector based on given probabilities.
\+ Added a function to pick randomly unique rows from a matrix.
\+ Added a Heaviside step function.
\+ Added function to swap argument values.
**Optimisation**
\+ Added a MATLAB Memetic Algorithm (MA) implementation.
\* The algorithm calls provided functions and can solve generic problems.
**Control**
\+ Added tonal control in the frequency domain.
\* Control is contained in a single function.
\* Can be used with or without virtual sensing.
\* Implementations of optimal control and FxLMS (still frequency domain) calculations are available.
**Signal Processing - Array Processing**
\+ Added array manifold (steering vector) calculation function.
**Signal Processing - Generic**
\+ Added frequency band calculation function with 1/1 octave and 1/3 octave bands.
\+ Add fractional delay filter impulse response generation function.
**Virtual Sensing - Generic**
\+ Added a multiple coherence calculation function.
**Virtual Sensing - Remote Microphone Technique**
\* Divide the observation filter and estimation with observation filter in two functions. The return arguments are split appropriately to the function they relate.
\+ Added option to include noise in the monitoring microphone power spectral density matrix with specified SNR value.
**Sound Fields**
\+ Added plane wave calculation function.
\+ Added Circular Harmonics calculation function.
\+ Added Spherical Harmonics calculation function.
\+ Added Discrete Circular Fourier Transform (DCFT) calculation function.
