function Answer=inputdlg(Prompt, Title, NumLines, DefAns)
%INPUTDLG Input dialog box.
%  Answer = inputdlg(Prompt) creates a modal dialog box that returns
%  user input for multiple prompts in the cell array Answer.  Prompt
%  is a cell array containing the Prompt strings.
%
%  Answer = inputdlg(Prompt,Title) specifies the Title for the dialog.
%
%  Answer = inputdlg(Prompt,Title,LineNo) specifies the number of lines
%  for each answer in LineNo.  LineNo may be a constant value or a 
%  vector having one element per Prompt.
%
%  Answer = inputdlg(Prompt,Title,LineNo,DefAns) specifies the default
%  answer to display for each Prompt.  DefAns must contain the same
%  number of elements as Prompt and must be a cell array.
%
%  Example:
%  prompt={'Enter the matrix size:','Enter the colormap name:'};
%  def={'20','hsv'};
%  title='Input for Peaks function';
%  lineNo=1;
%  answer=inputdlg(prompt,title,lineNo,def);
