Hi,
I made a list of 4-dimensional vectors using the following code.
\startluacode
local matT = {{0,0,1,1/3},{1,0,0,1/3},{0,1/2,0,1/3},{0,1/2,0,0}}
local matOld = {{1/4},{1/4},{1/4},{1/4}}
local matNew = {}
local matHistory = {}
table.insert(matHistory, matOld)
for i = 2, 15 do
matOld = matHistory[i-1]
matNew = mtx.product(matT, matOld)
-- mtx.typeset(matT)context("\\times")mtx.typeset(matOld)
-- context(" = ") mtx.typeset(matNew) context("\\blank")
table.insert(matHistory, matNew)
end
\stopluacode
I’d like to draw a line graph of the data in matHistory to show the change of
each component of 4-dimensional vectors.
How can I draw it in LuaMetaFun?
In the manual, data is already given in the example.
How can bring the data made in lua to ConTeXt?
Thank you.
Best regards,
Dalyoung
