MATLAB: Index exceeds matrix dimensions error

exceeds matrix dimension errorindex

hi i was running this simple code,but i got this error,any idea how to fix it?

L = 140;                     % Length of signal         
NFFT = 2^nextpow2(L); % Next power of 2 from length of y
YY = fft(rawdata,NFFT)/L;

((((((((((Index exceeds matrix dimensions.))))))))

Error in Untitled2 (line 11)
YY = fft(rawdata,NFFT)/L;

How can you take 256 samples from an array with 140 samples? Maybe you need to pad it with zeros or something

newArray = [oldArray, zeros(1, NFFT - length(oldArray))];

My apologies - stupid mistake has been located. A variable representing minutes shares the function name "min".

check the syntax of the sum() function

Syntax

B = sum(A)
B = sum(A,dim)
B = sum(..., 'double')
B = sum(..., dim,'double')
B = sum(..., 'native')
B = sum(..., dim,'native')

Your statement isum=sum(indi,:) is invalid. Maybe you mean isum=sum(indi(:));
