Hi I have (.mat) file containing 19 cropped data as shown in the figure. How can I convert it to (.wav) ?I dont want to convert it one by one.I got this code from a friend, but the (.wav) are empty. Also, the .wav produced are not the same count as the original cropped(I cropped 19 it gave me 25 (.wav)). If the sampling frequency is the issue, I followed the Fs of the original .wav(before I cropped). The code is:
fs = 44100 %change to your sample rate
load('result.mat');
data = whos;
for i = 1:length(data)
wavwrite(data(i).name,fs,num2str(i));
end
Thanks a lot, Hope somebody will help.

W = load('result.mat');
fn = fieldnames(W);
for i = 1 : length(fn)
wavwrite( W.fn{K}, fs, num2str(i));
end

Hi @Walter Roberson, Thanks..however I got this error: Undefined function or variable 'K'.
Error in convert_to_wav (line 4) wavwrite( W.fn{K}, fs, num2str(i));
