If you are tasked with maintaining a system based on MATLAB 7.1, these resources still apply:
% Append note to audio signal audio_signal = [audio_signal, note_signal, silence]; matlab 7.1
Some research groups wrote custom C-MEX files or Fortran MEX files using compilers (like LCC or Visual Studio 2003) that no longer work with modern MATLAB. MATLAB 7.1 preserves that investment. If you are tasked with maintaining a system
% Parameters fs = 8192; % Sampling frequency (Hz) duration = 0.5; % Duration of each note (seconds) tempo = 120; % Beats per minute This allowed memory-efficient programming
MATLAB 7.1 offered robust support for int8 , uint8 , int16 , uint16 , int32 , uint32 , int64 , and uint64 , along with logical arrays. This allowed memory-efficient programming, crucial for image processing and embedded systems work.
