so now here...

Code: Select all

output (Math.log(@f1))

def Math.log(*p)
log(*p)
end

output (log(@f1))

nice try, 110, but "stack level too deep". hmpf.

def log(*p) #the definition of your new function
Math.log(*p) #the execution code
end

in C it would look like this, just to see what we're doing:
float log(*args)
{
return Math.log(*args);
}

so i know two working methods now to choose from.

here is the next issue. for noise with chi distribution i need to trigger this

((Math.sqrt(-2.0*Math.log(1.0-(rand))))*(Math.cos((rand)*6.283185307))**2.0)

for n times and accumulate the result.

no idea how to do that in ruby - and no idea how to make 5 consecutive triggers from 1 outside the ruby object.

both would be a good exercise.

#using Range object. passing .each method executed the code in {} brackets once for each integer in the range
(0...100).each{ 
|i| #this line is optional - it puts current value into variable i
#your code
}

#same as the one before, but it return array containing all the results.
(0...100).map{ 
|i|
#your code
}

#or alternatively, this does the same as above.
Array.new(100){
|i| #index within the array
#your code
}
