如下:
function generate_all_the_graphes()
% generate all the graphs from the data with data name
clear;clc;
for index=0:1:5
sub_plot_one_graph(index);
end
function sub_plot_one_graph(i)
%subroutine to plot each graph for each data sheet in the current folder
name =sprintf('%08d',i);
full_name = ['xyzbead' name '.dat'];
fid =fopen(full_name,'r');
[data,count]=fscanf(fid,'%f');
%%以后就是赋值、plot、saveas的顺序了,因为出错就在上面这部分,故下面的略掉%%
运行后老说
??? Error using ==> fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in ==> sub_plot_one_graph at 7
[data,count]=fscanf(fid,'%f')%% fscanf() input the chosen data to assign the variable vector "data"
我单独运行子程序(先设好index),看的到有fid产生,但从主程序开始运行却说fid不正确,然后导致文件打不开。搞不懂怎么回事?是参数传递的写法不正确吗?还是程序本身有问题?高手能教教我吗?今天整了一整天就是想整出这个程序来。先谢过了。
