%function fmt = tablefmt(Wd,number)
% jdc 12-Oct-02
%PURPOSE:
% Construct a format for printing an arbitrary number with specified
% field width and precision, using e.g. fprintf
%INPUT:
% Wd - field width and precision (example: 12.3)
% Note: field width 'W' must be >= 7 for
% exponential formats to print correctly
% number - numerical value for which the format is to be constructed
%OUTPUT:
% f or e format specification as string variable
%EXAMPLE:
% number = 0.123456789012345678; W = 12; d = 3;
%for i = -3:15,
% val=(-1)^i*number*10^i;
% fmt=tablefmt(12.3,val);
% fprintf([ fmt '\n'],val);
