Error with audio from pushbutton
显示 更早的评论
Hi! I am trying to make some pushbuttons in Matlab. When I press each pushbutton, I want that every one of them to play a sound. I have this error while pressing one of the buttons:
I get the same error for this line: x = A*s;. I am also plotting the graphs of each variable that I want to play as sound, and when I plot them, I don't get any error.
Could you please help me?

@Monika Grezer - can you show all of the code for one of your push button callbacks? Also, please describe what A is, how many dimensions, what the line A = A/max(max(max(A))); is supposed to be doing.

Do you have a variable named max?

Sending code privately is not the nature of this forum. The idea is to provide help for free, if the solution is available for the community.
You cannot store 2 audio signals in a 2x2 matrix, because this matrix have 4 elements only. This would be an extremely short sound. The error message is possible only, if A has more than 3 dimensions. Check this again.

A = abs(randn(n, m));
what is m? Could it be that this variable is set to zero?

push3 assumes that global variable A has been set, but your code here does not set it. Your first function builds and returns A, without storing it in the global A.

You have that function
semnaleamestecate
that returns A as its second output.
In the place that you call semnaleamestecate you should be writing to the global A there (or in some calling function that you return A to.)

A = A ./ max(A(:));
My guess at the moment is that your A is empty.
