 function varargout = nInputSeries(varargin)

+// Count the number of input output data series
+// 
+// Calling Sequence
+// ioData = nInputSeries(plantData)
+// 
+// Parameters
+// plantData : iddata type module
+// ioData : structure type variable having input and output object
+// 
+// Description
+// plantData must be iddata type. The function returns the number of input and output data series in struct form. It has two fields name as input and output.  
+// 
+// Examples
+// plantData = iddata(rand(100,3),rand(100,2),0.1)
+// ioData = nInputSeries(plantData)
+// 
+// Examples
+// plantData = iddata(rand(100,2),[],0.1)
+// ioData = nInputSeries(plantData)
+// 
+// Examples
+// plantData = iddata([],rand(100,3),0.1)
+// ioData = nInputSeries(plantData)
+// 
+// Authors
+// Ashutosh Kumar Bhargava, Bhushan Manjarekar
