Weight Converter Pounds to Kilograms: Matlab

Problem

Create a variable pounds to store weight in pounds. Convert this to kilograms and assign the result to a variable kilos. The conversion factor is 1 kilogram = 2.2 pounds. Solve using Matlab

Solution

This problem has been taken from the book written by Stomy Attaway. This is a problem in the first chapter. This book is really great for the beginners to become a professionals in Matlab. I seriously recommend reading this book: Matlab, Third Edition: A Practical Introduction to Programming and Problem Solving.

Okay lets go into the solution. This is a very basic problem and can be solved in many different ways. We will solve this problem taking the input from user and then give the output. If you don't understand the problem then go to explanation section below the program section and if you still don't understand then check out these links which will give teach you about the basics behind this program.

1) Input in Matlab

2) Variables in Matlab
3) fprintf in Matlab

Program

%Ask the user for input of pounds
pounds = input('Enter the weight in pounds');
%Convert pounds to kilos using the conversion factor 
kilos = 2.2*pounds;
%Display the weight in kilos
fprintf('The weight of %f pounds is %f kilos\n',pounds,kilos)

You can also solve this problem using functions if you will repeatedly use the conversion.

Explanation

I will explain this problem line by line and you can understand this easily. In the first line we are using the input function in Matlab to ask the user to enter the value of weight in pounds. Now we will use the conversion factor of 1 kg = 2.2 pounds to convert the value of pounds to kilos. Notice that we are storing the value of the weight of the object in Kilograms to kilos. Then we are using the fprintf statement to display the value to the user.

Problem 60 Project Euler Solution with python

Prime pair sets The primes 3, 7, 109, and 673, are quite remarkable. By taking any two primes and concatenating them in any order the result will always be prime. For example, taking 7 and 109, both 7109 and 1097 are prime. The sum of these four primes, 792, represents the lowest sum for a set of four primes with this property. Find the lowest sum for a set of five primes for which any two primes concatenate to produce another prime. This problem is j u st a brute force problem. If you have come here because you don't know the limit upto which you will h ave to gener ate the prime numbers t hen go ahe ad and t r y with 10,000 . When I first start ed solving the problem I chose 1 million(beca use most of the problem s on project E uler have this limit ), but it took very long for the computer to fin d the solution. After searching on the internet then I found many people choosing 10, 000 so I have changed my in put f rom 1 million to 10000 and the output was f ast. He

Add/Embed SVG to Blogger website

In this post I will tell you my method(trick) of adding SVG images in a blogger website or blog. Before starting , the first thin g I am assu m ing is that you are aware of SVG if you are here. If not please see S calable V ec tor G raphics Recently when I tried to embed a SVG image for a post on pygal, I tried uploading the SVG file and blogger Image uploader came up with an error, because of which I had to find some other way. SVG File upload Error in Blogger I started sea rc hing Google " Embed SVG in Blogger " . I found blogorrhea , w h ich gave some i nformatio n on add ing SVG directly as a markup , which worked , but I faced another problem using this . Also th is guy has used lot of Javascript which was confusin g for me, being new to using SVG. So I first t houg ht of learning on h ow to embed SVG in HTML and t his on e worked out. Actually we can embed SVG in HTML i n following ways: Using Object tag Using Iframe tag Using embed tag Us

Making a quiz web app with python and flask

Edit : When you are creating a web app with h tml templates, then y ou will have to sa ve the html file in templates folder in the Current Wor ki ng Directory( CWD). If you save the file in the C W D directl y you will get a TemplateNotFound error. Thank you Udhay for pointing it out. In this post we will create a quiz website using python . I will be using the flask framework . After reading this tutorial you will learn form submission , flask templates , python code in flask templates , shuffling the questions and options with the random module and few others. Please note that this tutorial is not big as it seems to be. Some of the code has been rewritten to maintain consistency and also font size is somewhat big so that your eyes won't get stressed reading this tutorial. Also the content has not occupied the full width of the page. In this tutorial I am assuming that you are having a very basic understanding of the flask framework . Please refer the documentation
