Drawing procedure

Draw([equation set],[variable set],[parameter name], [list of ranges for the variable],[range for the parameter], parameter increment for the storage,epsilon,epsiloni,Sens);where the arguments are the same than the previous procedure. It returns a

with(ALIAS): with(plots): Draw([x^2+(y-1)^2+z^2-1,x^2-y^3],[x,y],[z],[[-100,100],[-100,100]],[[-2,2]], 0.05,1e-6,1);Note that optionally you may add two arguments at the end of the list of arguments. These arguments are the name of a C++ program and the name of the procedure that is defined within this program. This procedure must update the range of the unknowns according to the value of the parameter.

Note that the points used for drawing the plot are stored in the file
`/tmp/Branch1` for the first branch, `/tmp/Branch2` for the
second branch and so on.

For problems involving more than 2 variables you may obtain partial
plots by using the `DrawND` procedure, see
section 9.10.
