We describe a new robust ab-initio real-space code based on (i) density functional theory, (ii) finite element method and (iii) environment-reflecting pseudopotentials. This approach brings a new quality to solving Kohn-Sham equations, calculating electronic states, total energy, Hellmann-Feynman...

The computer program CALFEM is written for the software MATLAB and is an interactive tool for learning the finite element method. CALFEM is an abbreviation of ”Computer Aided Learning of the Finite Element Method” and been developed by the Division of Structural Mechanics at Lund University since...
is_finite() //判断是否为有限值。 hypot() //计算一直角三角形的斜边长度。 hexdec() //把十六进制转换为十进制。 fmod() //显示随机数最大的可能值。 fmod() //返回除法的浮点数余数。 floor() //向下舍入为最接近的整数。 expm1() //返回 exp(x) - 1,甚至当 number 的值接近零也能计算出...

In the above code, you define tuples that hold the constraints and their names. LpProblem allows you to add constraints to a model by specifying them as tuples. The first element is a LpConstraint instance. The second element is a human-readable name for that constraint....

Elements of NumPy arrays are also all of the same data type leading to more efficient and simpler code than using Python’s standard data types. NumPy数组的元素也都是相同的数据类型,这使得代码比使用Python的标准数据类型更高效、更简单。 By default, the elements are floating point numbers. 默认情...
