System NxN - system solver vs. Linear Algebra Pro Utilizzo e statistiche
An easy to use application for solving systems of n linear equations in n variables.
This calculator is intended for students, engineers and anyone who needs to solve systems of linear equations with up to 11 unknowns.
You can solve systems up to 11 equations in landscape mode and to up to 5 equations in portrait mode.
To solve a system of linear equations, select the number of equations, type in the coefficients of linear equations and tap Solve. Supports integers, fractions, mixed numbers and decimals. You may enter positive, negative, or zero values.
Shows results as decimals and fractions.
Round results to specified precision:
• Decimal results can be rounded to 0-9 decimal places, so you may round results to the nearest 10ths, 100ths, etc. By default, the app is set up to round to 3 decimal places. If you need to round results to the nearest whole number, please select 0 decimal places.
• Rounding fractions to the nearest 1/2, 1/4, 1/8, 1/12, 1/16, 1/32, 1/64, 1/128, 1/256. If you do not need to round fractions, just select "-" (selected default).
Stores history with the possibility to recall previous equations.
Sends results and history via email.
