You can get solutions with the least-squares method even if overdetermined systems (the number of equations is greater than the number of variables). It is written in C++. C++11 or later is required.

\(y = x + 3\) is a linear equation and \(y = x^2 + 3x\) is a quadratic equation. If the product of two numbers is zero, then one or both numbers must also be equal to ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...

Systems of equations can be modelled as matrices in order to solve them The concept and example illustrated below explain the calculations that occur: $$ A \begin ...

Abstract: In this paper, five iterative methods for solving two coupled fuzzy Sylvester matrix equations are considered. The two coupled fuzzy Sylvester matrix equations are expressed by using the ...
