WarnWave = [sin(1:.6:400), sin(1:.7:400), sin(1:.4:400)];
Audio = audioplayer(WarnWave, 22050);
play(Audio);

Need something similar to this, which gives a sound when the Whatsapp message comes, or an incoming SMS. A whooshing or a swishing sound.
What structure of WarnWave will give such a notification sound?

I agree, but for alerts you never know.

So here is an absolutely ugly Windows XP hack that gets the SystemExclamation sound from the registry and replaces environment variables with the correct values and then plays the sound.
[~, tempStr] = system('reg query HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default\SystemExclamation\.Current');
[~, valueStart] = regexp(tempStr, 'REG_EXPAND_SZ ');
soundStr = tempStr(valueStart+1:(end-1));
envVarSymbol = strfind(soundStr, '%');
while length(envVarSymbol) >= 2
soundStr = [soundStr(1:(envVarSymbol(1)-1)), ...
getenv(soundStr((envVarSymbol(1)+1):(envVarSymbol(2)-1))), ...
soundStr((envVarSymbol(2)+1):end)];
envVarSymbol = strfind(soundStr, '%');
end
[x, Fs] = wavread(soundStr);
sound(x, Fs)
I need to think about this idea more. Interfaces really should be playing system sounds (yuk, who actually has system sounds set to on) at the appropriate times.

'wavread' incorrect.
