Weight converter Kilograms to Pounds: Matlab

Problem

Create a variable kilos to store the weight in kilograms and convert it into pounds using Matlab. Show the result in a neat text fashion. The conversion factor is 1 Pound = 0.453592 Kilograms.

Solution

This problem has been a sequel of the recent post on radiusofcircle.blogspot.com and can be found here: Weight to convert Pounds to Kilograms. This post is similar to that and if you have solved the prequel post then I suggest you to solve this problem by your own and verify the solution with the one posted here. In this problem we will request the user to input the value of the weight in kilograms and store it in a variable. Now we will use the conversion factor and store the value of the result in another variable. We will finally display the value to the user.Some of the key concepts in that you need to know in Matlab to solve this problem are as follows:

1) Input function in Matlab

2) Matlab Variables

3) fprintf function in Matlab (OR)

4) disp function to display the output in Matlab

I suggest you to know about both fprintf and disp functions, but for now if you know any one of them you can manage to solve this problem. Checkout the explanation of the program below the program section if you didn't understand the program.

Program

%Ask the user to input the weight in Kilograms
kilos = input('Enter the weight in Kilograms: ');
%convert kilos to pounds using conversion factor
pounds = 0.453592*kilos;
fprintf('Weight of %f kilos is %f pounds\n',kilos,pounds)

I have named this file as kilos_to_pounds.m for using this is Matlab command line interface.

Explanation

The above code is simple if you know the basics of Matlab. In the above code we are taking the input of the user asking to Enter the weight in kilograms. Then we convert the kilos to pounds using the conversion factor 1 pound = 0.453592 kilos. Finally we print the output in a very user friendly way so that the user will understand it easily.

I have tried to explain the code so that it will be easy even for the beginners to understand. If you have any doubt or didn't understand any part of the program then please do contact me from here: contact me, or comment below. This will not only help you but also help others.

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
