I'm new to Matlab.
I'm writing a matlab function to which I have given the arguments: Params, X,Y
All 3 are vectors.
I want to find out how many rows vector X has.
What is the corresponding matlab command/inbuilt function?
I was thinking of using :
MStruct = get(DMObj)
PropertyValue = get(DMObj, 'NRows')
Any better suggestions please?

Try size(x) to give you the size of the vectors
doc size
