Function: chart - show a table of function values
chart(heading, values, flag);
heading - a list of expressions, each depending on the first member of the list
values - a list of expressions, which are to be substituted for the first member of heading .
flag - a boolean value.
This prints a table of values of one or more expressions (using "table" in the ordinary sense of the word, rather than its technical meaning in Maple), in the form of a matrix.
The first row of the matrix is the value of heading . This is a list of expressions, each of which contains the first entry (which is typically a variable x ).
Row of the matrix, for from 1 to the number of items in values , is obtained by substituting values[n] for x in heading and evaluating it.
If the third argument flag is omitted or true, then each entry is evaluated numerically using evalf .
If a member of heading is a function that should only be evaluated with numerical arguments, you can delay evaluation by placing single quotes around it, e.g. 'f(x)' .
This function is part of the Maple Advisor Database library, and must be loaded before use by the command readlib(chart); .
