[ Матрица калькулятор ] PRO 4+

I’m a retired electrical engineer. Thirty-five years ago when I was a student at Texas A&M, we had to solve linear algebra problems by hand for our mechanical engineering, electrical engineering, physics and math classes. Sometimes the professor could only give us no more than four problems on a test because of the time it would take to invert even a 3x3 matrix — and one little sign error on the matrix inversion could totally mess up your solution. This app is simple to use and gives instant results. I do a little “free lance” design work and this app will be a time saver that I can pass on to the client. Good job developers !!!

Thank you, sir. Your words are like fuel for our motivation. If you find something worth adding to the app do not hesitate to contact us! :) Happy New Year 2k21!

This app really helps in my algebra class. It is worth the price! My only complaint is that there is no clear button, so when I need to type a new matrix in I either have to quit the app or go through a long process of just pressing delete over and over to delete my current matrix.

Hi, try to long press on the delete button it should remove the whole matrix quicker. If you have any question please contact us, thanks for the review!
