tropicalsparse.add
function adds the provided inputs in Tropical Algebra based on type of
Tropical Algebra.
1 | tropicalsparse.add(A, B, store = NULL, algebraType)
|
A |
is matrix or vector. |
B |
is matrix or vector. |
store |
is storage technique. |
algebraType |
is string input that can be |
The compulsory inputs of the function tropicalsparse.add
are A
, B
and
algebraType
while the remaining input is optional that is store
. The inputs A
and
B
can be matrix/matrix, matrix/vector, vector/matrix and vector/vector otherwise the function generates
an error. For A
and B
, the order of the input does not matter. It can be in any of the following
way: the first input of the function is matrix and second input is a vector. Similarly, vise versa.
store
can be coo
, csc
and csr
for applying following storage techniques
respectively: Coordinate-Wise, Compressed Sparse Row, Compressed Sparse Column. This input is case sensitive.
If the store
input is other than the specified storage techniques then the function generates an error.
The input algebraType
is used to specify type of Tropical Algebra. This can be minplus
or
maxplus
. For more details about algebraType
, see detail
section of
check.infinityM
or check.infinityV
. tropicalsparse.storage
function is used to apply storage technique depends upon the input given. If store
input is not
specified then the functionality will be performed without using any storage technique.
Addition of A
and B
in Tropical Algebra.
