iptcheckmap

Check validity of colormap

Syntax

• iptcheckmap(map,func_name,var_name,arg_pos)
  

Description

iptcheckmap(map,func_name,var_name,arg_pos) checks the validity of the MATLAB colormap and issues an error message if it is invalid.

func_name is a string that specifies the name used in the formatted error message to identify the function checking the colormap.

var_name is a string that specifies the name used in the formatted error message to identify the argument being checked.

arg_pos is a positive integer that indicates the position of the argument being checked in the function argument list. iptcheckmap converts this value to an ordinal number and includes this information in the formatted error message.

Example

• bad_map = ones(10);
  iptcheckmap(bad_map,'func_name','var_name',2)
  

The following shows the format of the error message and indicates which parts you can customize using iptcheckmap arguments.
