这是一个高速多维插值算法。当我们建模以后，原始的算法可能极为复杂和低速，在现有的计算条件下要得到最终的结果甚至要让我们等白了头，而该模块可以让复杂低速的计算变得简单迅速，甚至瞬间得到结果。它的原理是通过原始模型算法计算出有限的栅格节点，构建出一个多维栅格，而后可以无限次的对多维输入值瞬间得出对应的输出值，而得到的结果跟通过原始算法得到的结果相差无几。

　　并且，该模块还提供了对输入、输出值的校准功能。

　　该模块限定的输入、输出值为８位或16位的整数，浮点的计算也可以先变换为整数后再进行高速处理，得到结果后再反变换回去，这对于绝大多数采样是完全足够的。

　　该模块中包含了足够的源文件，都是以标准C编制的，可以在任何编译环境下进行编译，并且还有调用例子供参考。接口定义见imdi.h文件。-This is a high-speed multi-dimensional interpolation algorithm. When we model after the original algorithm can be extremely complex and slow. In the current calculation under the conditions to be the final outcome even let our other white head, The module allows complex low-speed calculation is simple and quick, and even get instant results. It adopted the principle of the original model algorithm calculated the limited grid nodes to construct a multi-dimensional grid. the latter can be an unlimited number of multi-dimensional import value reached instantaneous value of the corresponding output, and the results obtained through the original algorithm with the results comparable. In addition, the module also provides a pair of input and output value of the calibration. The module limited in
