Error, (in plot3d) at least three arguments are required

 

Description

Examples

Description

  

For users of Maple 18 and earlier versions: This error occurs when plot3d is not passed the minimum number of arguments it requires to plot a three-dimensional surface.

  

In order to plot a three-dimensional surface, plot3d requires the following parameters:

• 

the expression, function, or operator describing the surface

• 

the range of values for the first variable

• 

the range of values for the second variable

  

Note: Unlike the plot command, plot3d does not assume default ranges for the plotting variables. Not giving both ranges is a common cause for this error.

  

To correct this error, provide plot3d at least three arguments.

Examples

Example 1: Using an expression for the three-dimensional surface

The following Maple input tries to plot z=x33xy2, but it does not specify the ranges for the variables x and y.

plot3dx33xy2

Error, (in plot3d) at least three arguments are required

 

Provide ranges for x and y to correct the error.

plot3dx33xy2,x=20..20,y=20..20

Example 2: Using a functional operator for the three-dimensional surface

This example uses a functional operator, f, to define the surface.

fu,vvu

fu,vvu

(1)

plot3df

Error, (in plot3d) at least three arguments are required

 

For functional operators, ranges must be given in the form a..b, not as equations.

plot3df,1..1,1..1
