+## @deftypefn {Function file} {@var{P} =} inputdlg (@var{PROMPT} [,@var{TITLE} [,@var{ROWSCOLS}, @var{DEFAULTS}]])
+##
+## Returns the user's inputs from a multi-textfield dialog box in form of a cell array of strings.
+## If the dialog is closed by the Cancel button, an empty cell array is returned.
+##
+## @table @samp
+## @item PROMPT
+## The first argument @var{PROMPT} is mandatory.
+## It is a cell array with strings labeling each textfield. 
+## @item TITLE
+## The optional string @var{TITLE} can be used as the caption of the dialog. 
+## @item ROWSCOLS
+## The size of the text fields can be defined by the argument @var{ROWSCOLS}, 
+##  which can have three forms:
+## - a scalar value which defines the number of rows used for each text field.
+## - a vector which defines the individual number of rows used for each text field.
+## - a matrix which defines the individual number of rows and columns used for each text field.
+## @item DEFAULTS
+## It is possible to place default values into the text fields by supplying
+## the a cell array of strings or number for the argument @var{DEFAULTS}.
+## @end table
