# Simultaneous equations (Complex) Calculator

## Calculates the solution of simultaneous linear equations with n variables. Variable are allowed input of complex numbers.

 For input of complex number, please refer to "Description rule of expression" $\normal{\left[\begin{array}\vspace{10} a_{\small 11}& a_{\small 12}& \cdots& a_{\small 1n}\\\vspace{10} a_{\small 21}& a_{\small 22}& \cdots& a_{\small 2n}\vspace{20}\\ \vdots& \vdots& \ddots& \vdots\vspace{10}\\a_{\small n1}& a_{\small n2}& \cdots& a_{\small nn}\\\end{array}\right]} {\left[\begin{array}\vspace{10} x_{\small 1}\\\vspace{10} x_{\small 2}\vspace{20}\\ \vdots \vspace{10}\\x_{\small n}\\\end{array}\right]}={\left[\begin{array}\vspace{5} b_{\small 1}\\\vspace{5} b_{\small 2}\\ \vdots \vspace{5}\\b_{\small n}\\\end{array}\right]}\\$
