%                                vep.m
%  Scope:  This MATLAB macro computes the value of the vertical error 
%          probable (VEP).
%  Usage:  yvep = vep(y)
%  Description of parameters:
%          y     - input, error vector containing the errors on y axis
%          yvep  - output, vertical error probable (VEP) value

end

for  k = 1:nrowy
   ytemp(k) = abs(ymean - y(k));
