Priority: medium
Bug ID: 81267
Assignee: [email protected]
Summary: Repeat operator
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: UNCONFIRMED
Version: unspecified
Component: Formula Editor
Product: LibreOffice
I request an enhancement of the formula editor to support the repeat operator
using the big R notation proposed by Yingxu Wang. The repeat operator is the
mathematical equivalent of a for-loop. It works similar to the summation
operator except that the operation can be any mathematical operation. For
example, the generalization of the summation operator could be expressed like
this:
sum from i = 1 to k x_i = repeat from i = 1 to k "sum"(x_i)
Here "repeat" would render the big R sign similar to the big summation sign.
See for instance:
"On Contemporary Denotational Mathematics for Computational Intelligence" by
Yingxu Wang
Any workaround for the current formula editor is welcome for now (how to render
a big R).
