Axes and Angle to Ellipsoid Matrix
Description
Transforms two numbers (variances of independent directions) and an angle to an
ellipsoid matrix.
Usage
axesAngle2Covariance(Variance2D, Angle)
Arguments
Variance2D
[1:2] Variance from two independent directions (data axes or
more simple: standard deviation of data from first and second dimensions
respectively).
Angle
Numerical value defining the angle between the main ax of an
ellipsoid to the standard cartesian system.
Value
CovarianceMatrix2D
[1:2, 1:2] Numeric matrix containing the covariance
matrix.
