of F. The question marks indicates uncertainty or non-definition. For example,
for X<0, LN(X) is not defined, thus the X lines shows a question mark in that
interval. Right at zero (0+0) F is infinite, for X = e, F = 1/e. F increases before
reaching this value, as indicated by the upward arrow, and decreases after this
value (X=e) becoming slightly larger than zero (+:0) as X goes to infinity. A
plot of the graph is shown below to illustrate these observations:

Function DRAW3DMATRIX

This function takes as argument a n m matrix, Z, = [ z ], and minimum and
ij
maximum values for the plot. You want to select the values of v and v so
min max
that they contain the values listed in Z. The general call to the function is,
therefore, DRAW3DMATRIX(Z,v ,v ). To illustrate the use of this function
min max
we first generate a 6 5 matrix using RANM({6,5}), and then call function
DRAW3DMATRIX, as shown below:
The plot is in the style of a FAST3DPLOT. Different views of the plot are shown
