No idea how to use [hist] in Pure Data.
And the three arguments of [hist] is:
I cannot figure out the first and second argument meaning? And how am I going to pass the output of [hist] to [tabwrite] and generate an array diagram in Pure Data.
It seems you are using the [hist] object from smlib.
The histogram will contain <number of classes> bins of equal size, with the first bin being equivalent to the <value of first class> and the last bin being equivalent to <value of last class>-1 (the offset is arguably a bug).
So, the value of first class is the minimum expected input value (x>=min), and the value of last class is the maximum expected input value (x<<max).
Any input value exceeding those boundaries will be clipped.
[3, absolute(
|
[hist 2 5 3]
|
[print]
This will create a 3-bin histogram, with the bins 2±0.5 (with clipping this means x<2.5), 3±0.5 and 4±0.5 (with clipping that is 3.5<x).
The input 3 will be filed into the second bin, so the absolute histogram is 0 1 0.
[3, absolute(
|
[hist 3 6 3]
|
[print]
This will create a 3-bin histogram, with the bins 3±0.5, 4±0.5 and 5±0.5.
The input 3 will be now filed into the first bin, so the absolute histogram is 1 0 0.
You can set the table-values by sending a list of number to the table, prefixed with the starting index:
[relative(
|
[hist 0 100 100]
|
[list prepend 0]
|
[s $0-histo]
[table $0-histo 100]
Alternatively check the [array] object (which also can be accessed via [tabread] and the like)
