Function
definitions in APL
 |
A
typical sequence to demonstrate that the derivative of the integral returns
the original function consists of:
x <-
100 sample 0 3
y <-
exp -x*2
Iy <-
S (mids y) x d x
DIy <-
(d Iy) % d x
plot (y vs x) and (DIy
vs mids x)
vs is a function that delivers the lists
y
and x to the plot function in the required form; while function
and delivers several tables to plot. |
APL*PLUS III workspace, APLMM.w3,
may be downloaded for the functions.
[Readers with browsers that do
not display the fonts we intended, should note the following equivalences
above:
<-
is a left pointing arrow, x is
the multiplication sign and % is
the division sign.]
