用于进行各种复杂的计算和数据处理，如SUM（求和）、AVERAGE（平均值）、VLOOKUP（垂直查找）Excel基本结构 五、Apache POI基本操作 由于Excel分为03版本和07版本，所以我们在使用的时候需要 注：处理03版本excel时，主要使用HSSFWorkbook、HSSFSheet、HSSFRow、HSSFCell等对象来操作Ex

a least squares approach, for which we put the problem in matrix form. If we write up all the blend shapes (which are deltas to the base mesh) as one large matrix A, where each column holds the delta of a single blend shape, then the composite delta is given by Ax = b, where ...

The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. The method declaration has the following form: Copy public static void main(String[] args) In source-file mode, the java command can launch a class declared...
