mindistance.m

i was not knowing matlab in depth so i have sent simple basic programs

function d = minDistance(x,y,z)
% Find the min distance between a set of points and the origin
nPoints = length(x);
d = zeros(nPoints,1); % Preallocate
for k = 1:nPoints % Compute distance for every point
d(k) = sqrt(x(k)
