Hello, can anyone help me with this error with the code shown bellow?
if true
samplingRate = 11025;
%transform the signal to the frequency domain.
%fourierData = fft(data,length(data));
%magFour = abs(fourierData);
totalFileTimeInMSec = (length(data) / samplingRate)*100;
frameLengthInMSec = 1;
% calculate the number of frames
numberOfFrames = totalFileTimeInMSec / frameLengthInMSec;
numberOfFrames = floor(numberOfFrames);
% calculate the size of each frame in the data array.
frameSize = samplingRate * frameLengthInMSec / 100;
%initialize the frames.
% frames = zeros(numberOfFrames,frameSize);
% frame = zeros(1,frameSize);
frames = numberOfFrames;
frame = frameSize;
% copy the data from the signal to the frames.
startIndex = 1;
endIndex = frameSize;
for frameM = 1:1:numberOfFrames
frame = data(startIndex:endIndex,1);
startIndex = startIndex + frameSize;
endIndex = endIndex +frameSize;
frames(frameM,:) = frame.';
end

You define frames to be a single scalar number:
frames = numberOfFrames;
but you seem to be indexing into it as if it were an array.

Why did you change
% frames = zeros(numberOfFrames,frameSize);
to
% frame = zeros(1,frameSize);
frames = numberOfFrames;
frame = frameSize;
The first was working, and adding more definitions, partially as comment, overwriting the former one, is confusing only, obviously.
