| 1 | TMtxVec *Log10() const; | Log base 10. |
| 2 | TMtxVec *Log10(TMtxVec *X) const; | Calculate the log base 10 for all X elements. |
| 3 | TMtxVec *Log10(int Index, int Len) const; | Calculate the log base 10 for calling object elements [Index]..[Index+Len-1] in-place. |

Overload 1: TMtxVec *Log10() const;
Log base 10.
Remarks:
Calculate the log base 10 for all calling object elements in-place.
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
a.SetIt(DewArray<double>{ 1.0, 2.0, 4.0, 10.0 });
a.Log10();
Vector expected;
expected.SetIt(DewArray<double>{ 0.0, 0.301029995663981, 0.602059991327962, 1.0 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
throw tException("Vector.Log10: mismatch");
}#include "MtxExpr.h"
#include "Units.MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxExpr;
void Example()
{
Vector a, b;
a.SetIt(false, DewArray<double>{10, 100, 1000, 10000}); // a = [10,100,1000,10000]
a.Log10(); // a = [1,2,3,4], same as:
a = Log10(a);
b.Log10(a); //same as
b = Log10(a);

Overload 2: TMtxVec *Log10(TMtxVec *X) const;
Calculate the log base 10 for all X elements.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TMtxVec * |
Remarks:
Store the results in the calling object. Size and Vector::Complex properties of the calling vector are set implicitly to match the X object.
Examples

#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
Vector x;
x.SetIt(DewArray<double>{ 1.0, 2.0, 4.0, 10.0 });
a.Log10(x);
Vector expected;

Overload 3: TMtxVec *Log10(int Index, int Len) const;
Calculate the log base 10 for calling object elements [Index]..[Index+Len-1] in-place.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | int | |
| 2 | Len | int |
Remarks:
An exception is raised if Vector::ConditionCheck is True and array borders are overrun.

Overload 4: TMtxVec *Log10(TMtxVec *X, int XIndex, int Index, int Len) const;
Calculate the log base 10 for X elements [XIndex]..[XIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TMtxVec * | |
| 2 | XIndex | int | |
| 3 | Index | int | |
| 4 | Len | int |
Remarks:
Store the results in the calling object elements [Index]..[Index+Len-1]. Size and Vector::Complex properties of the calling object must be set explicitly. An exception is raised if Vector::ConditionCheck is True and array borders are overrun.
