implementing a sigmoid function in the [vexpr] object

March 1, 2011 | 11:48 am

Hi,

I am not a math person, and I have been staring at the following links:
http://en.wikipedia.org/wiki/Sigmoid_function
http://en.wikipedia.org/wiki/Probit

http://en.wikipedia.org/wiki/Weibull_distribution

- does anyone have a clue how to implement the equations at these links in a [vexpr] object?
… I currently play with Tristan Jehan’s [mapper] object, but I am not sure if I can make it work …

I would like to distribute a list of 1/4 beat times (0, 0.25, 0.5 0.75 of total meter time) according to the above listed curve functions, so that the beats times are offset according to the curve. The total time of the 4/4 beats should be a variable included in these functions …

Thanks for your help,

ana
