function str=vec2str(v,form)
%VEC2STR  Converts vector to string array.
%         VEC2STR(V,'form') returns a string array with
%         one row for each number in the vector, V.
%         The input argument 'form' is optional and specifies
%         the format for the number to string conversion.
%         If 'form' is missing the default ' %.4g' is used.
%         This gives a leading space befor the number.
%         See SPRINTF in a C manual for valid formats.
