hello,
i am trying to import (x) which is an audio signal and then concatenate with some zeros but get the following error message. can anyone please help.
cheers,
x = uiimport('test_signal.mat')
input_signal=x; B = zeros([1,8]); total_input_signal= [B input_signal];
??? Error using ==> horzcat The following error occurred converting from double to struct: Error using ==> struct Conversion to struct from double is not possible.
Error in ==> output at 10 total_input_signal= [B input_signal];

if the mat - file contains one variable
x = uiimport('test_signal.mat');
names =fieldnames(x);
xx = x.(names{:});
total_input_signal = [zeros(1,size(xx,2));xx];

if it is a real sound file like
x=load('handel')
x =
y: [73113x1 double]
Fs: 8192
you will have a structure as well. For any set of variables you save and load again, the variables will be behind a structure. To perform array/matrix operations on the sound data in this case, you can think of
total_input_signal=[B ; x.y];
If it is still not clear to you, can you specify what variables youre file test_signal.mat is made up by?
