## This function computes Spherical Error Probable ...

This function computes spherical_error Probable radius from inputs consisting of the square roots of the eigenvalues of a covariance matrix (equivalently, from sigma-x, sigma-y, and sigma-z, of a trivariate normal distribution in a coordinate system where there is no cross-correlation between variables. ) This means that if you have a covariance matrix and wish to compute the S. E. P. , simply obtain the square roots of the eigenvalues and use these as inputs. For example, list them via "sqrt(eig(C))" where C is your covariance matrix.

The S. E. P. is the radius of a sphere which contains a fraction of probability equal to the input "prob, " which is asumed to be 0. 5 if omitted.

Note: if one of the input sigmas is significantly smaller than both others, calculation time may rise.

By uncommenting a labeled line of code, the user can enter a diagnostic mode toacy of this algoracy of this algor inputs are speci inputs are specified.
