TSparseMtx.Rem Method

Overload List

#SignatureDescription
1TMtxVec Rem(TMtxVec X, TMtxVec Y)The Reminder after division X/Y.
└ indexed: TMtxVec Rem(TMtxVec X, TMtxVec Y, Int32 XIndex, Int32 YIndex, Int32 Index, Int32 Len)
2TMtxVec Rem(TMtxVec X, Double Y)Calculates reminder after division X/Y.
└ indexed: TMtxVec Rem(TMtxVec X, Double Y, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec Rem(TMtxVec X, TMtxVec Y)

The Reminder after division X/Y.

#NameTypeDescription
1XTMtxVecsource TVec or TMtx
2YTMtxVecsource TVec or TMtx

Result: stored in self (calling object), returns self for chaining

Remarks:

Calculates reminder after division according to formula:

x[i]-y[i]*Trunc(x[i]/y[i]).

The results will be saved to the calling vector. X and Y must be a real and have the same length. Size and Dew.Math.TMtxVec.Complex properties of the calling vector are set implicitly to match the X object.

Examples
Matrix a;
Matrix b;
Matrix c;
a.SetIt(1,4,false,new double[] {0,1,10,-1,-10}); // a = new double[] {0, 1, 10,    -1, -10};
b.SetIt(1,4,false,[0,1,PI,-1,-PI]); // b = [0, 1, PI,    -1, -PI];
c.Rem(a,b);                     // c = new double[] {0, 0, 0.5752, 0, -0.5752}

Indexed: TMtxVec Rem(TMtxVec X, TMtxVec Y, Int32 XIndex, Int32 YIndex, Int32 Index, Int32 Len)

Calculates reminder after division X/Y.

#NameTypeDescription
1XTMtxVecsource TVec or TMtx
2YTMtxVecsource TVec or TMtx
3XIndexInt32X start index
4YIndexInt32Y start index
5IndexInt32start index
6LenInt32element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Calculation uses the following formula:

z[i] = x[xi]-y[yi]*Trunc(x[xi]/y[yi]),

where i in [Index..Index+Len], xi in [XIndex..XIndex+Len], yi in [YIndex..YIndex+Len]. The results will be saved to the calling vector. X must be a real. An exception will be raised if Dew.Math.TMtxVecBase.ConditionCheck is True and array borders are overrun.

Overload 2: TMtxVec Rem(TMtxVec X, Double Y)

Calculates reminder after division X/Y.

#NameTypeDescription
1XTMtxVecsource TVec or TMtx
2YDoublescalar

Result: stored in self (calling object), returns self for chaining

Remarks:

Reminder is calculated by using the following formula:

x[i]-y*Trunc(x[i]/y).

X must be a real. The results will be saved to the calling vector. Size and Dew.Math.TMtxVec.Complex properties of the calling vector are set implicitly to match the X object.

Indexed: TMtxVec Rem(TMtxVec X, Double Y, Int32 XIndex, Int32 Index, Int32 Len)

Calculates reminder after division X/Y.

#NameTypeDescription

2YDoublescalar
3XIndexInt32X start index
4IndexInt32start index
5LenInt32element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Reminder is calculated by using the following formula:

x[i]-y*Trunc(x[i]/y).

X must be a real. The results will be saved to the calling vector. An exception will be raised if Dew.Math.TMtxVecBase.ConditionCheck is True and array borders are overrun.
