# MathSample
|
||
|
||
Generates a random sample from the array elements.
|
||
|
||
Version for working with an array of real values:
|
||
|
||
```
|
||
bool MathSample(
|
||
const double& array[], // array of values
|
||
const int count, // count
|
||
double& result[] // array of results
|
||
)
|
||
|
||
```
|
||
|
||
Version for working with an array of integer values:
|
||
|
||
```
|
||
bool MathSample(
|
||
const int& array[], // array of values
|
||
const int count, // count
|
||
int& result[] // array of results
|
||
)
|
||
|
||
```
|
||
|
||
Version for working with an array of real values. It is possible to obtain a sample with replacement:
|
||
|
||
```
|
||
bool MathSample(
|
||
const double& array[], // array of values
|
||
const int count, // count
|
||
const bool replace, // flag
|
||
double& result[], // array of results
|
||
)
|
||
|
||
```

int& result[] // array of results
|

)
|
||
|

```
|
||
|
||
Version for working with an array of real values, for which the probabilities of sampling are defined.
|
||
|
||
```
|
||
bool MathSample(
|
||
const double& array[], // array of values
|
||
double& probabilities[], // array of probabilities
|
||
const int count, // count
|
||
double& result[] // array of results

||
Parameters
|
||
|
||
array[]
|
||
|
||
[in] Array of integer values.
|
||
|
||
probabilities[]
|
||
|
||
[in] Array of probabilities for sampling the elements.
|
||
|
||
count
|
||
|
||
[in] The number of elements.
|
||
|
||
replace
|
||
|
||
[in] Parameter that allows sampling with replacement.
|
||
|
||
result[]
|
||
|
||
[out] Array to output the results.
|
||
|
||
Return Value
|
||
|
||
Returns true if successful, otherwise false.
|
||
|
||
Note
|
||
|
||
The replace=true argument allows performing random sampling of the elements with replacement back to the original sequence.
