Integral menggunakan Metode Numerik di Python dan Plot Fungsi menggunakan Matplotlib.

Kode berikut digunakan untuk mencari nilai integral dari a ke b sebuah fungsi f(x).

Saya menggunakan modul Numpy untuk fungsi pangkat (power).

from pylab import *
import numpy as np

def f(x):
    y = np.power(x,3)+np.power(x,2)+x+1
    return y

dx = .1
a = 0.
b = 1.

x = a
c = 0.  # untuk menampung hasil integral
while x<=b:
    y  = f(x)
    c += f(x)*dx
    x += dx

print 'hasil integral dari ',a,' ke ',b,' adalah ' ,c

#untuk plotting
x = np.arange(-10., 10., .01)
y = f(x)

plot(x,y)
grid(True)
show()

List Files on Certain Google Drive Folder and It's Subfolders

...and display it in html format using div tag with border so the files in subfolders will displayed in box, and files in other subfolder will displayed in other box. If subfolder have subfolder, then files inside that sub-subfolder will displayed inside box inside box, :s :P :D

The Algorithm itself is bit like this previous post. OK, I copy and paste a little bit of,..., ok most of code from it.

All by Google App Script.

I use string variable named text to receive all output.

Basically, after the script is completely executed, the content of variable text is complete html source code.

:)

Here it is

Code.gs

function listFilesNFolders(form) { 
 var text = ''; 
 var lv = 2; //for level depth 
 var home = DriveApp.getFolderById('0BxZS62a5NdNYUGxySmp2QW41OUU'); 
 text+='<br><h'+lv+'>'+home.getName()+'</h'+lv+'>' 
 var NIM = home.getFoldersByName("aa"); 
 if(NIM.hasNext()){ 
  var NIMfold = NIM.next(); 
  text+='<br><h'+lv+'>'+NIMfold.getName()+'</h'+lv+'>'; 
  text = crawl(NIMfold,text,lv); 
 } else{ 
  text+='<br> Anda belum mengupload tugas'; 
 } 
 Logger.getLog();
  return text; 
} 

function crawl(home,text,lv){ 
 lv++; 
 var files=home.getFiles(); 
 text+='<div id="p'+lv+'"style="border: 1px solid black;">'; 
 while (files.hasNext()){ 
  var file=files.next(); 
  text+='<br>'+file.getName();
  } 
 text+='</div><br>'; 
 var folders=home.getFolders(); 
 while (folders.hasNext()){ 
  var folder=folders.next(); 
  text+='<br><div id="p'+lv+'"style="border: 1px solid black;">'; 
  text+='<br><h'+lv+'>'+folder.getName()+'</h'+lv+'>'; 
  text = crawl(folder,text,lv); 
  text+='<br>'; text+='</div>'; 
 } 
 lv--; 
 return text; 
} function 
doGet(e) { 
 return HtmlService.createHtmlOutputFromFile('form.html'); 
}

..
form.html

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
    <style>
    input { display:block; margin: 20px; }

    #p1 { position: relative; left: 10px;}
    #p2 { position: relative; left: 20px;}
    #p3 { position: relative; left: 30px;}
    #p4 { position: relative; left: 40px;}
    #p5 { position: relative; left: 50px;}
    #p6 { position: relative; left: 60px;}
    


    h1 { position: relative;margin-left: 10px;font-weight: bold;}
    h2 { position: relative;margin-left: 20px;font-weight: bold;}
    h3 { position: relative;margin-left: 30px;font-weight: bold;}
    h4 { position: relative;margin-left: 40px;font-weight: bold;}
    h5 { position: relative;margin-left: 50px;font-weight: bold;}
    h6 { position: relative;margin-left: 60px;font-weight: bold;}

    </style>
  </head>
  <body>
 
 <form id="myForm">
    <input type="submit" 
    value="OK"        
    onclick=
    "
    this.value='Proses';
    google.script.run.withSuccessHandler(fileUploaded).listFilesNFolders(this.parentNode);
    return false;
    "
                    >
  
</form>

<div id="output"></div>

<script>
    function fileUploaded(status) {
        document.getElementById('myForm').style.display = 'none';
        document.getElementById('output').innerHTML = status;
    }
</script>
    
  </body>
</html>

Look at the HTML code, the key for indentation is <px> tag with x = 1,2,3,4,5,6. The bigger the number, the more left margin increased. I modify the <hx> tag too.

The content of text variable after script's completely executed.

Yeah, it looks like garbage, but it's actual html code and if we open it in web browser, it will looks like this.

Passing String Variable to a Function on Google App Script

I have text a variable with string type, I want to pass it to a function and change the value there just like previous post (using list type)

but, text variable value can't be changed by passing to function like list (or array). I didn't have append or push syntax.

well, we can still use list

but list have comma, :(

so I updated the value by passing it to a function like this

function htmlOutput(form) {
  var text = 'Tadaa...';
  text+='Test'; 

text = dummy(text);
  return text;
}

function dummy(text){
text+='hehehe';
  return text;
}

:)

By definition, keripik pisang is pisang goreng, :D

Hanya Kemungkinan.

Akan seru jika di Valencia nanti para rider (sambil cengingisan) minggir memberi jalan Rossi tuk bertarung dengan Lorenzo.

(seru dan aneh, :) )

(well, kecuali Marquez mungkin, :) ).

(gak mungkin, :) ).
