Hello guys,

when I applied this code show me this error. please, can you help me to fix it.

the error is:

Hi give the input for those arguments For Eg: function oneRoundWSN(numNodes,grid,receiver) This function is there know, Take only this code oneRoundWSN(numNodes,grid,receiver) and give argument values like oneRoundWSN(10,0,2), paste in command box and press enter you will get a result .. Thank you
