Linear Equation

A linear equation is expressed by formula \(a1\cdot v1+a2 \cdot v2+a3 \cdot v3+\ldots +an \cdot vn+c=0\), where a1, a2, a3, …, an, c are constant coefficients, and v1, v2, v3, …, vn are scalar equation variables. You can create a linear equation by calling

constraint_item GCE_AddLinearEquation(GCE_system gSys, const double * a, 
                                     const var_item * v, 
                                           size_t n, 
                                           double c),

that returns a descriptor of the linear equation registered in the gSys system.

Initial method call data are given below:

• gSys is a constraint system;

• a is an array of constant coefficients for variables;

• v is an array of linear equation variables;

• n is a number of linear equation variables;

• с is a constant coefficient c that is not multiplied by any variable.
