Error : Not enough input arguments

Hello all,

I am new to matlab , and i am getting not enough input arguments error while running one code which i got from google ,

kindly help me to resolve the error

code:

function [P]=simRangeData(N,iN,S,iS)

pwrSig=10.^(S/10);

pwrNoise=10.^(N/10);

nRangeGate=iN(end);

voltNoise_I=zeros(nRangeGate,1);

voltNoise_Q=zeros(nRangeGate,1);

I=length(iN);

iLead=1;

for i=1:I

iLag=iN(i);

voltNoise_I(iLead:iLag)=sqrt(pwrNoise(i)/2)*randn(iLag-iLead+1,1);

voltNoise_Q(iLead:iLag)=sqrt(pwrNoise(i)/2)*randn(iLag-iLead+1,1);

iLead=iLag;

end

noise=voltNoise_I+j*voltNoise_Q;

signal=zeros(size(noise));

I=length(iS);

for i=1:I

pwrSwerling=exprnd(pwrSig(i),1,1);

signal(iS(i))=sqrt(pwrSwerling/2)+j*sqrt(pwrSwerling/2);

end

data=signal+noise;

P=abs(data).^2;

How do you call this function? Do you press the green triangle in the editor? Then no inputs are provided. You have to call this from the command window or from another function as:

P = simRangeData(N,iN,S,iS)
%                ^^^^^^^^^  This must be provided as inputs

hey Jan,

thank you so much, i provided inputs, but now its showing following error,

Unrecognized function or variable 'iN'

I do not know, how iN is defined in your case. What is needed as 2nd input argument?
