ABAQUS Fortran学习的一个简单例子

基于最小二乘法的冗余信息数据融合算法实现(Least-squares method based on redundant information and data fusion algorithm)

线性方程组迭代解法,包括SOR，CG ，BICG等(linear system iteration solver)

可以进行简单的数学运算：加、减、乘、除,sin(),cos(),tan()等，还可以对数字进行取余和开方的运算。但仅限于十进制下，还可以进行数的正、负之间的相互转换，exit表示退出, clear表示初始化，有一个 TextField用于显示传来的计算结果；Server端用于监听连接请求、计算发送过来的两数的和、送回数据结果。(Can perform simple arithmetic: add, subtract, multiply, divide, sin (), cos (), tan (), etc. can also figure to take over and prescribing arithmetic. But only under the metric system can also be used for a number of positive and negative between the conversion, exit, said exit, clear that the initialization, there is a TextField to display the results from the calculation Server client connection requests for eavesdropping, calculated sent the two and the number of returned data.)
