figflag.m

基于ＭＡＴＬＡＢ的辅助设计 简述了矩阵分析的重要性

function [flag,fig] = figflag(str,silent)
%FIGFLAG True if figure is currently displayed on screen.
%       [FLAG,FIG] = FIGFLAG(STR,SILENT) checks to see if any figure 
%       with Name STR is presently on the screen. If such a figure is 
%       presently on the screen, FLAG=1, else FLAG=0.  If SILENT=0, the
%       figures are brought to the front.
