Compute volume under 2D-Gaussian

Compute volume under 2D-Gaussian

get_volume_gaussian_2D(X_sig, Y_sig)

Arguments

X_sig	numeric value(s) of the x-axis spread (sigma)
Y_sig	numeric value(s) of the y-axis spread (sigma)

Value

Numeric value(s) indicating the computed volume(s)

Details

Volume under the 2D-Gaussian is computed as: 2 * pi * sqrt(abs(X_sig)) * sqrt(abs(Y_sig))

Numeric vectors can be supplied to X_sig and Y_sig. If vectors of length greater than 1 are given, the function computes volume for each sequential pair of X_sig, Y_sig values. The lengths of these supplied vectors must be identical.
