Overload 1: TMtx CumSum
Cumulative sum for each of the matrix columns.
Result: stored in self (calling object), returns self for chaining
Calculate the cumulative sum for each of the calling matrix columns in-place.
Matrix Mtx;
Mtx.Size(false,3,2,[1,2,
2,5,
3,1]);
Mtx.CumSum;
// Mtx becomes:
// 1, 2
// 3, 7
// 6, 8Indexed: TMtxVec CumSum(Int32 Index, Int32 Len)
Cumulative sum.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | Int32 | start index |
| 2 | Len | Int32 | element count |
Result: stored in self (calling object), returns self for chaining
Calculate the cumulative sum for calling object elements [Index]..[Index+Len-1] in-place. An exception is raised if Dew.Math.Matrix.ConditionCheck is true and array borders are overrun.
Matrix a;
a.SetIt(2,2,false,new double[] {1,2,3,4};
a.CumSum(0,4); // a = new double[] {1,3,6,10}Overload 2: TMtx CumSum(TMtx Mtx)
Calculate tehe cumulative sum for each of the X matrix columns.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Mtx | TMtx | source TMtx |
Result: stored in self (calling object), returns self for chaining
Store the results in calling matrix. The Dew.Math.Matrix.Rows, Dew.Math.Matrix.Cols and Dew.Math.Matrix.Complex properties of the callig matrix are adjusted implicitly to match those of Mtx matrix.
Overload 3: TMtxVec CumSum(TMtxVec Vec, Int32 VecIndex, Int32 Index, Int32 Len)
Calculate the cumulative sum for Vec elements [VecIndex]..[VecIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVec | source TVec or TMtx |
| 2 | VecIndex | Int32 | |
| 3 | Index | Int32 | start index |
| 4 | Len | Int32 | element count |
Result: stored in self (calling object), returns self for chaining
Store the results in calling object elements [Index]..[Index+Len-1]. Size and Dew.Math.Matrix.Complex properties of the calling object must be set explicitly. Exception is raised if Dew.Math.Matrix.ConditionCheck property is True and array borders are overrun.
