Regression

I have been working on adding Regression to the calculator.  In this graph mode, points are entered and then a best fit line is calculated.

Above I have entered some points for linear regression.  The equation is then calculated and displayed at the top.  The equation can be changed between linear, logarithmic, exponential, power, quadratic polynomial or cubic polynomial.  When graphed, the points entered and equation will be drawn.

New features coming

The past couple of months I have mostly been focusing on bug fixes (I also haven't spent as much time working on the app).  I do still have plans to add more features to the app.

Currently, when in landscape orientation, the keyboard is at the bottom of the screen.  I had a request a few months ago for the option to place the keyboard on the left or right side of the screen in landscape mode.  I like this idea.  In the next release I will be adding this ability with a setting.  You will be able to choose between having the keyboard at the bottom, left, or right while in landscape mode.  Below is a screenshot of the keyboard on the right side.

I am also working on add regression to the calculator.  More information on this to come!

Version 1.7.4

I didn't end up getting the bug fix update out last week like I originally thought.  I finally got everything done last night and posted the update to Google Play.  This will be the last update and blog post for this year since I won't have much time to work on it over the Holidays.

More Bug Fixes

Well it has been a while since I have posted.  The hinge on my laptop broke a few weeks ago.  I was able to still use the computer but it was only a matter of time until it become unusable.  I bought a new laptop and now have everything setup on it to work on the app.

I am working on fixing some more bugs for the next update.  I should have it out sometime this week.

Bug Fixes and Engine Improvements

For the next update, I am working on fixing bugs and optimizing the engine.  Some more complicated problems are taking much longer to simplify than they should.  After the improvements I have made for the next update, some of these are now simplifying over 10 times faster than the current version.

I am also working on fixing some reported crashes when executing some problems or graphing some equations.

Custom Keys Released

Version 2.7 is now on Google Play.  This adds custom keys to the paid version.  I have also added a tutorial for custom keys on the website.  Click here to view tutorial.

Custom Keys Almost Here

Just through I would give a quick update since it has been a while since I posted about Custom Keys.  I am almost finished adding Custom Keys to the app.  If all goes well the custom keys update will be on Google Play next week.  I will also be adding a tutorial on the website on how to create custom keys.
