Assigning scalar elements
Scalar values of valid type can always get assigned to all left hand side element specifications:
- single element addressed (trivial case, described here)
- sequentially addressed ranges of elements (described here)
- regulary addressed ranges of elements (described here)
The scalar value assigned will than replace all elements addressed as shown in the following example:
ILArray<double> A = ILMath.ones(4,3);
// A is now:
//(:,:)
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
// set elements of the last columns to 55
A[":;end"] = 55.0;
// - or -
A[null,2] = 55.0;
// A is now:
//(:,:) 1e+001 *
// 0,10000 0,10000 5,50000
// 0,10000 0,10000 5,50000
// 0,10000 0,10000 5,50000
// 0,10000 0,10000 5,50000 In the next example we will assing the scalar value -333.3 to some elements by sequential indexing:
ILArray<double> A = ILMath.ones(4,3);
ILArray<int> ind = ILMath.toInt32(ILMath.rand(2,2)*12);
// A is now:
//(:,:)
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
// 1,00000 1,00000 1,00000
//
// ind (may) is now:
//(:,:)
// 3 8
// 10 5
// set random elements to -333.3
A[ind] = -333.3;
// A is now:
//(:,:) 1e+001 *
// 0,10000 0,10000 -33,33000
// 0,10000 -33,33000 5,50000
// 0,10000 0,10000 -33,33000
//-33,33000 0,10000 5,50000
