2017-05-01 Thread Dominique Laurain
Hello Robert, I wonder why you want to use the "abs()" function, when the "absolute value" function has no meaning for complex numbers. How you define the 'greater than' (>) operator in complex numbers ? It is hazardous to mix symbolic computing (var, sqrt,..language) and field operatorsbec

[sage-support] Transforming a complex function f:C->C into a function g:R^2->R^2

2017-05-01 Thread Robert Jacobson
I am wanting to hand off a holomorphic function to an external library, but the library only works with real numbers (operations with C++ doubles). Thus I wish to have Sage compute functions u and v for which f(x+i y) = u(x,y) + i v(x,y) such that u and v are expressed only in terms of operatio

2017-05-01 Thread Dima Pasechnik
IMHO you are the 1st one reporting about building Sage with gcc 7.0.0. It's not surprising - most probably the corresponding upstream packages, gsl and R in this case, have not yet been ported to gcc 7. On Monday, May 1, 2017 at 12:58:49 AM UTC+1, Tae Lim Kook wrote: > > Sorry if a similar messa
