用Fortran编程求解简单的一元二次方程案例(Solving quadratic equation of one variable)

摩擦力是抵抗固體表面，流體層和材料元件相對滑動的相對運動的力。有幾種類型的摩擦：幹摩擦是一種與之相反的力(friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the)

用牛顿法，共轭梯度法，最速下降法完成矩阵的计算(Newton conjugate gradient method)

converts a binary undirected adjacency graph into a hypergraph. The output is a non symmetric matrix where the columns are the vertices and the rows are the hyper edges.
