Item(System.Range,System.Range)

Property

Summary

The submatrix spanned by the given rows and columns, for example

a[1.., ..]

for every row of a matrix but the first, or

a[..2, 1..3]

for the first two rows of its second and third columns.

Remarks

Both extents have to be written out. A matrix indexed by one number gives a row
while a vector indexed by one number gives an element, so a single range would
have to mean one thing here and the other there --
https://github.com/asc-community/AngouriMath/issues/443.

Exception "ArgumentOutOfRangeException"

Thrown if either range reaches past the matrix.

Exception "InvalidMatrixOperationException"

Thrown if either range is empty, since a matrix has at least one row and one
column.
