Why am I getting the error "Array indices must be positive integers or logical values."?

function [Fluindex ] = find_Findex(Signal,timeframe,SampRate,slide )
%FIND_Kurtosis Summary of this function goes here
% Detailed explanation goes here
channels=size(Signal,2);
nFrames=size(Signal,1)/(timeframe*SampRate);
Fluindex=[];
if slide <=0
partition=1;
else
partition=slide/timeframe;
end
for f = 1:partition:nFrames
start_ind =((f-1)*timeframe*SampRate)+1;
end_ind = f*timeframe*SampRate;
Fluind_frame=[];
for i= 1:channels
Findex = zeros(2,3,4);
size(Findex)
Fluind_frame = zeros(3,4,5,6);
size( Fluind_frame)
Fluind_frame(:,i)= Findex (Signal(start_ind:end_ind,i));
end
Fluindex=cat(1,Fluindex,Fluind_frame);
end
end
when i run above code its show error like this.
Error using find_Findex
Array indices must be positive integers or logical values.
"why its showing like this??"

I don't think what you are showing us is not the complete error. There is no line 34 in the function.
Show us the complete code which gave you this error along with the inputs so that it will help us to help you.

It's a FAQ, probably the #1 most FAQed FAQ.
