Advanced data handling
Import can import data from two types of files, TXT and BMP. If you
don't specify "data type" Eudox will look at the extension of the file
to know whether to load the file as a TXT or BMP.
We place the file "prime.txt" in our Eudox directory. To load the file
in to Eudox and store the values to the variable 'a' you do like this.
This shows the values in a plot.
Here is a file were we have entered pairs of values. The two values at
each line are separated by a tab.
This loads the file prime2.txt in to Eudox and store it in 'a'.
This loads and displays a bmp.
This create a file named "test.txt" and save the values in 'a' in to
Fit is a very useful function to analyse data. It tries to fit a line
to some data points and return the best possible line to the data. This
is very important and is often used to calculate a constant out of data
observed in an experiment.
Fit assume that the first value in 'a' (2) has x-value 0, the second
(3) 1 and so on. This loads almost the same values but now the x coordinate
Note that the result from Fit is a bit different. This is because now we specified that the first y value (2) should have the x value 1 instead of 0.
This gives some info about the data variable 'a'.
This create a real random number between -3 and 5.7
"type" can be "Real" or "Integer". If you don't give any elements Random
will random 0 or 1. This creates a table with random integers from 0 to
