Generate an input data array to train the neural network

A simple loop-in-loop program.


%matlab code 
clc; clear all; close all;
A=[0.1, 0.2, 0.3, 0.1, 0.1, 0.2]; % assumed initial value
B=[0.5, 0.1, 0.1, 0, 0.2, 0.1];
C=[0, 0.2, 0.2, 0.4, 0.1, 0.1]; 
final=[];
r=1;
for i= 0:10
    for j=0:10
         for k=1:10
sum_up=(i*A+j*B+k*C);
                total=sum(sum_up);
                result=sum_up/total;
                row=[i, j, k, result];
final(r,:)=row;
                r=r+1;

How to import JPG/JPEG image into AutoCAD 2009?

It's very hard to find the right button on the menu (or navigation panel ?)of AutoCAD 2009. So just type the command:

IMAGEATTACH

That's it!

A GREAT way to reduce the .TIF file size while keep same high quality

Use Microsoft Office Picture Manager to open the original .TIF file, then export, set export size to 100%, DONE!

I had a >70MB .TIF image with 10000*10000 pixel, after applying this method, the image was shrinked to ~3MB. It's still 10000*10000 pixel and the quality is still good. That's amazing!

Use Sigmaplot to export high quality .TIF/.TIFF file

Sigmaplot is a powerful tool for drawing scientific charts, and it is also powerful at exporting high quality .TIF/.TIFF file, which can be directly submitted to the journal editors. Here's what I found out how to get high quality images from Sigmaplot:

Firstly, scale down the original graph. The default size of charts are relatively big, usually ~100mm*100mm. It's better to scale them down to 30%. Then select the items, and use highest DPI possible (for me, 600DPI). And change the exporting size to about 3 -5 time larger than the chart size. This will give you a large and clear TIF image.
