Warning: Integer operands are required for colon operator when used as index. How can I rectify this?

This is my code and I'm using R2021a.

clear all;

[signal,fs] = audioread('sample.wav');

f_d = 0.025;

f_size = f_d*fs;

n = length(signal);

n_f = floor(n/f_size);

temp = 0;

for i = 1 : n_f

frame(i,:) = signal(temp + 1 : temp + f_size); % Warning is showed here;

temp = temp + f_size;

end

if mod(n_f,2) == 1

frame(n_f+1,:) = zeros(size(frame(1,:)));

n_f=n_f+1;

end

save('framed');

Make sure that your variable f_size is an integer, perhaps something like this solves your problem:

f_size = round(f_d*fs);% ceil or floor should also work if you prefer either

It works.Thank you
