Why does the Signal Processing Toolbox 6.1 (R13SP1) cause

The issue with Signal Processing Toolbox 6.1 (R13SP1) causing MATLAB to crash when using the `BUFFER` function with a cell array input is due to a bug in the way `BUFFER` handles cell arrays cause MATLAB to ...](https://www.mathworks.com/matlabcentral/answers/96747-why-does-the-signal-processing-toolbox-6-1-r13sp1-cause-matlab-to-crash-when-i-use-buffer-with-an). This bug leads to an assertion failure and a crash cause MATLAB to ...](https://www.mathworks.com/matlabcentral/answers/96747-why-does-the-signal-processing-toolbox-6-1-r13sp1-cause-matlab-to-crash-when-i-use-buffer-with-an).

 Workaround

To avoid this issue, you can convert your cell array to a numeric array using the `CELL2MAT` function before passing it to `BUFFER` cause MATLAB to ...](https://www.mathworks.com/matlabcentral/answers/96747-why-does-the-signal-processing-toolbox-6-1-r13sp1-cause-matlab-to-crash-when-i-use-buffer-with-an). Here’s how you can do it:

% Example cell array
a = {1; 2; 3; 4; 5; 6; 7};
% Convert cell array to numeric array
b = cell2mat(a);
% Use BUFFER on the numeric array
c = buffer(b, 2);

By converting the cell array to a numeric array, you can avoid the crash and use the `BUFFER` function as intended.
