Matrix Calculator for Android

The application is designed to entering, storing and processing matrices. Direct matrices operations are: - sum; - subtract; - multiplication; - inversion (by the method of Gauss and the method of the square root); inversion of triangular matrix; .- multiplication of matrix by vector; - transposition; - multiplication of the vectors; - calculating - a determinant, trace and norm. The application allows to run a chain of successive operations on matrices and vectors
The application works with data stored in a database (DB) type SQLite named matrixCalculate.db with initial installation of the application is available for execution (or the menu of startup activity) function initsilizirane DB ("ins database" - initsilizira DB). Upon initial installation of the application is available for execution (or from the menu of startup activity) function initiate data base .With the implementation of this function database are initsilized and show examples of data that can be erased and resume work.
The application has a function for export, import and send the database and file containing the data of selected matrix to a file named MatrixFile.txt. The import and export operate in main memory of the device. With the sending can be selected recipient, for example Skype, e-mail and others.. When sending and saving can not be selected in any directory and under what name to be sent the data file as opposed to the application AdvanceMatrixCalculator.
