Rene Hansen modified a comment on ticket #4306
Hi Robert Yes, it was not a bug or change in maxima. The only change is wxMaxima not displaying ascii(9) ascii(11) etc anymore - but that it another forum.. Thanks for your time/help. /Rene'

Arghh... my colleague has apparently decided to change "Vertical tab" (ascii 11) with "Horizontal tab" (ascii 9) in the data files Also, the previous versions of maxima/wxMaxima has chaged the display of the string from: "Old" maxima/wxMaxima: headerLine : readline(Stream); "189.184875�22.000000" map(cint, charlist(headerLine)); [49,56,57,46,49,56,52,56,55,53,9,50,50,46,48,48,48,48,48,48,13] "New maxima/wxMaxima : headerLine : readline(Stream); "189.18487522.000000" map(cint, charlist(headerLine));...

Hi Robert There is no error message, the readline() reads the lines from my csv-file without any complains. However when the data in the csv-file are separated by tabs = ascii(11) the readline() removes the tab character. For example : If a line in the csv is 189.443924 {tab} 0.427444 readline reads it as 189.4439240.427444 which makes it impossible to separate the two numbers. Previously this as worked like a charm - readline() reads 189.443924 {tab} 0.427444 so I could use split( dataLine, ascii(11)...

Reading tab-delimited datafiles

Hi Robert Sorry for my delay. I am doing some mathematical work with the data afterwards :-) I am trying to increase the memory available to Maxima, it does not seem to work. I am probably doing something wrong: -X " --dynamic-space-size 2000"

My task is that I have a data file containing 933252 lines of data like this: 2022.03.29 20:57:13 nan nan nan nan 210 nan 1 nan 233 2 6.6703 1.00677 19.187 100 0 3 Where each cell is a measurement result of a certain quantity e.g. pressure, temperature etc I would like to plot the 933252 measurements of each quantity e,g, the temperature. I have made my own function to read in the raw data from the csv-file which works quite well. the individual data is easily separated: ["2022.03.26","19:35:57","nan","nan","nan","nan","120","nan","0","nan","153","0","6.78323","1.02828","27.312","100","0","3",""]...

Cannot create wery large data array

I tried to run the above code on the latest nightly build version="branch_5_44_base_372_g042a6e8a7",timestamp="2021-04-06 23:55:46",host="x86_64-w64-mingw32",lisp_name="SBCL",lisp_version="2.0.0" I could not get it to fail either. I will see if I can create a test that reproduces the failure. Your suggestion to rethink linearinterpol sounds quite interesting - also possibility of a speed-up.

For some years ago, I have been using this function a lot without having this problem - it seem like this might be due to some changes in maxima in the meantime. Unfortunately I can not tell exactly when this error has occurred because I haven't been using this function for while... The each set of data "Data[n]" is an array of [x, y] data with 2068 data points.... The dataset "ActualSpectrometer" is also an array with 2068 [x, y] data. for GasNumb : 1 thru NumberOfDatafiles do ( kill(SplinesFit,...
