Project description
It is necessary to approximate the heat conductivity equation using an explicit scheme by the method of certain coefficients. We just need an approximation, that is, finding indefinite coefficients, if to find them you need to solve a system of equations to solve it. I just can't understand how approximation is done with this method.
