| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVec | source TVec or TMtx |
Result: stored in self (calling object), returns self for chaining
Copy each of Vec elements to the calling object. Size and Dew.Math.Matrix.Complex properties of the calling object are set implicitly to match Vec object.

throw new Exception("Matrix.Copy: mismatch");Matrix a;
Matrix b;
Matrix c;
a.SetIt(1,2,true,new double[] {1,2,3,4}); // a = new double[] {1,2,3,4}
b.Copy(a); // b = new double[] {1,2,3,4}
c.Copy(a,b); //concatenate a and b and store in c = new double[] {1,2,3,4,1,2,3,4}Indexed: TMtxVec Copy(TMtxVec Vec, Int32 VecIndex, Int32 Index, Int32 Len)
