zoziha / auto-diff Goto Github PK

Hello! First of all thanks for developing this! I find automatic differentiation very exiting and an incredible tool for my work

I'm trying to use this library for a project, but for some reason I can't get any derivatives values. Not even the examples are running for me:

demo1: y = (a + b*b)*exp(c)
 y     =    3.00000000    
 dy/da =    0.00000000    
 dy/db =    0.00000000    
 dy/dc =    0.00000000    
 
 demo2: y = (a + b)*(b + 1.0)
 y     =    6.00000000    
 dy/da =    0.00000000    
 dy/db =    0.00000000  

This happens on all examples

Any idea about what could this be?

I also tried the recommended fazang library but couldn't even link it to a simple main program :/

I suggest adding the topic automatic-differentiation since that has many more repos than auto-diffferentiation .
