LinEv1D
AnalysisLibErrType LinEv1D (double inputArray[], ssize_t numberOfElements, double multiplier, double additiveConstant, double outputArray[]);
Purpose
Performs a linear evaluation of a 1D array.
LinEv1D obtains the ith element of the output array, using the following formula:
yi = (a × xi) + b
LinEv1D can perform the operation in place; that is, the input and output arrays can be the same.
The following example uses the LinEv1 function.
double inputData[10], linearData[10];
double multiplier, additiveConstant;
AnalysisLibErrType status;
// Generate an array of random numbers
status = Uniform (10, 17, inputData);
multiplier = 0.5;
additiveConstant = 1.0;
status = LinEv1D(inputData, 10, multiplier, additiveConstant, linearData);
Parameters
| Input | ||
| Name | Type | Description |
| inputArray | double [] | The array used as the basis for the linear evaluation. |
| numberOfElements | ssize_t | Number of elements used in the linear evaluation of the input array. |
| multiplier | double | Multiplicative constant used in the linear evaluation of the input array. Default Value: 1.0. |

| Name | Type | Description |
| outputArray | double [] | The linear evaluation of the input array. |
Return Value
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
