I would like to ask please,
I defined the following functions :
h1(z)=(abs(z)-1)^2*(1+2*abs(z)), for -1<z<1 otherwise h1(z)=0.
and would like to compose h1(z(x,y))
I created two functions in FF++ but when I composed them, FF++ doesn’t compute the composed function.
func h1= ((abs(z)-1)^2*(1+2abs(z)))(z>-1 && z<1);
func utilde=h1(z(x,y));// compse h1(z)
but FF++ tells me that there is an error in the definition of utilde.
