Hey Guys and Gals ^^ I'm having trouble with Julia. Maybe one of you can help me out The program i am writing requires the linear-equation-system-solver(command "\") in the folder "Julia-0.4.5\share\julia\base\linalg". Now my problem is that i need the equation solved strictly on integers, an approximate solution is of no use to me, which is why i tried working with the "Rational" Type. Curiously, the solver seems to work for the Rational Type if and only if no pivoting is required. Otherwise, the following Error is thrown:
WARNING: pivoting only implemented for Float32, Float64, Complex64 and Complex128 ERROR: LoadError: OverflowError() in * at rational.jl:188 [inlined code] from linalg/generic.jl:471 in reflector! at no file:0 in A_ldiv_B! at linalg/qr.jl:346 in \ at linalg/qr.jl:398 in \ at linalg/dense.jl:450 in include at boot.jl:261 in include_from_node1 at loading.jl:320 while loading C:\users\<username omitted>\documents\julia-0.4.5\sg_project\v0.3\Test02.jl, in expression starting on line 3 Code to reproduce the Error: A=[[2//1,0//1] [3//1,3//2] [1//1,3//2]] v=[2//1,0//1] A\v Now i am under the impression that i could build a relatively simple workaround if i knew exactly where in the developer's code the actual problem is, but i am confused by the whole organization of the thing. Building my own solver could certainly be done, but this will most likely be ineffecient. Unfortunately, runtime is very important here, as the method i am currently devising is supposed to be embedded in some very expensive loops. I am a very unexperienced programmer and will likely not understand much programmertalk, but i am a mathematician and will probably have little problems in this respect. Maybe you have some ideas how to handle this problem. Thank you in advance for taking the time to look at my problem :)
