Description
|
|
|
•
|
The function compose(f,g) interprets the expressions f and g as functions of s and t, respectively, and returns an expression that represents the function f(g(t)). Here, s and t are the default symbols of f (given by findsym(f,1)) and g (given by findsym(g,1)), respectively.
|
|
•
|
The function compose(f,g,z) treats f and g as functions of s and t, as described above, and returns an expression that represents the function f(g(z)).
|
|
•
|
The function compose(f,g,x,z) treats f as a function of x, g as a function of the default symbol, and returns an expression that represents the function f(g(z)).
|
|
•
|
The function compose(f,g,x,y,z) treats f as a function of x, g as a function of y, and returns an expression that represents the function f(g(z)).
