MaxMin1D是NI Labwindows CVI开发环境中的一个系统函式，通过该函式可以获取一维数组的最大值、最小值以及最大值和最小值在数组中的序号。
基本介绍
- 中文名：获取一维数组最大值和最小值
- 外文名：MaxMin1D
概要
MaxMin1D函式返回输入数组中的最大值和最小值，以及最大值和最小值所在的位置，如果出现多个相等的最大值和最小值，MaxMin1D返回第一个值所在的位置，如果数组中所有元素值为NaNs（NotANumber，不是一个数），MaxMin1D返回最大值和最小值的索引（位置）为-1。
Finds the maximum and minimum values in the input array and their locations in the array. If there are multiple instances of the maximum and/or minimum values, MaxMin1D returns the location of the first occurrence. If all the elements in the input array are NaNs, MaxMin1D returns -1 for both the index of the maximum value and the index of the minimum value.
参考事例如下：
double inputData[10];double maximumValue, minimumValue;int maximumIndex, minimumIndex;AnalysisLibErrType status; // Generate an array of random numbersstatus = Uniform (10, 17, inputData);status = MaxMin1D(inputData, 10, &maximumValue, &maximumIndex, &minimumValue, &minimumIndex);
参数
Input/输入参数 | ||
Name/名称 | Type/类型 | Description/描述 |
inputArray/输入数组 | double [] | The array from which the maximum and minimum values and their locations within the array are determined. |
numberOfElements/元素个数 | ssize_t | Number of elements used in determining the maximum and minimum values. |
Output/输出参数 | ||
Name/名称 | Type | Description |
maximumValue/最大值 | double | Maximum value found in the input array. |
maximumIndex/最大值索引（位置） | ssize_t | The index of the maximum value found in the input array. |
minimumValue/最小值 | double | Minimum value found in the input array. |
minimumIndex/最小值索引（位置） | ssize_t | The index of the minimum value found in the input array. |
返回值
Name | Type | Description |
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
其它信息
使用MaxMin1D函式需添加如下头档案，系统会在编译的时候询问是否添加，所以该步骤可以省略！
