Convert from Degrees Fahrenheit to Degrees Celsius using Matlab

Problem

Create a variable ftemp to store a temperature in degrees Fahrenheit (F). Convert this to degrees Celsius (C) and store the result in a variable ctemp. The conversion factor is C  =  (F – 32) * 5/9. Solve this problem using Matlab. 

Solution

This problem has been taken from the book Matlab: A practical introduction to programming and problem solving. This book is really awesome book. The author assumes zero knowledge to programming. This book starts from variables and continues to Graphic User Interface using Matlab. Image processing using Matlab is also included in this book. I suggest you go through this book if you don't have any knowledge programming in Matlab or if you want to become an expert from Novice in Matlab programming.

Coming back to solving the above problem, in the question it was asked to to convert from degree Fahrenheit to degree Celsius using the conversion factor. This is similar to my previous post: Weight Conversion Kilograms to Pounds . I would suggest you first have a look at the program and if you don' t understand then have a look at the explanation section. The background concepts used in this program are as follows:
1) Variables In Matlab
2) Request user input in Matlab - Input function
3) fprint in Matlab OR
4) disp function in Matlab
Either 3 or 4 is sufficient to solve this problem but I suggest you to learn both so that it will be useful in the future.

Program


%Program to convert from F to C
%Take the input from user
ftemp = input('Enter your values in Degree Fahrenheit: ');
%Convert the values from F to C using the conversion factor
%C  =  (F – 32) * 5/9
ctemp = (ftemp-32)*5/9; 
%In the above statement you can also use (ftemp-32)*(5/9) or many other
%combinations to avoid any problems with operator precedence.
fprintf('%f F = %f C\n',ftemp,ctemp);
I have saved the above file as f_to_c.m on my computer.

Explanation

In the program we will take the user input using the input function and store it in ftemp variable. then we will convert the value of ftemp to ctemp using the conversion factor given and store it in ctemp variable. In the above program I have directly written the conversion factor because this will not cause any problem with operator precedence. If you feel that operator precedence has an effect on the statement then you can brackets and convert as (ftemp-32)*(5/9) or in many other combinations in the convenient way you feel. If you don't know about operator precedence, you are not going to face any problem solving this problem without having knowledge of operator precedence. But I suggest you to have a glance of the same here: Operator Precedence in Matlab. Coming back finally I have given the output to the user in a neat format using the fprintf statement.

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
